The causes for damage as a result of moisture and, subsequently, mold growth or accumulation of water, can be complex: a defective or improperly installed roof, cracks in the masonry, or damaged sealing elements at the various roof and wall penetrations. Thermal bridges caused by incorrect execution of construction work can also result in condensation, both visible and hidden, resulting in extensive damage. However, incorrect user behavior, such as a heating and ventilation routine that is not adapted to the building’s characteristics, can also be a cause of damage. If, for instance, an extremely well-insulated, well-sealed house is insufficiently ventilated or incorrectly heated, an excessively damp indoor climate may develop, promoting the growth of mold or causing condensation damage.

The Importance Of Investigating The Cause Of Moisture

In order to uncover such problems and subsequently remedy them expertly, a detailed building analysis must be performed by trained specialists. Bau-& Energieberatung Reto Niedermann GmbH, a building and energy consultancy based in Unterentfelden, Switzerland, works in this field; its experts specialize in building physics as well as construction design and energy planning. The firm prepares surveyors’ reports and provides detailed information to remedy moisture damage expertly. As virtually all associated remedial action can be very complex and thus very expensive, a well-founded investigation of the root causes is an absolute requirement. In addition to expert knowledge, complemented by practical experience, information collected using electronic data logging equipment contributes a great deal to ensuring that the required diagnostic work can be carried out accurately, in a well-founded manner, cost-effectively and quickly, and that it can be documented in detail.

In this context, the MSR145 mini data loggers of the MSR Electronics GmbH are very helpful. The loggers use their internal sensors to record temperature, relative humidity, air pressure, acceleration, and light intensity; when investigating building physics, the temperature, air pressure, and humidity data is of critical importance. However, recording acceleration values can also be helpful if it has to be established, for example, whether the loggers have been moved from one place to another. The measurements can be taken with an extremely high degree of accuracy over long periods of time. To this end, these miniature devices are capable of recording more than two million measured values, or with an optional microSD card, over one billion measured values. All data can be quickly transferred to a computer using the USB port or microSD card. Subsequently, it can be examined using the Analysis software supplied by MSR Electronics GmbH, with split-second resolution. These data loggers can also be supplied with analog inputs for very specific measuring tasks, for instance, in order to connect special external sensors for analyzing the air, measuring conductivity, or detecting moisture.

Diagnostic measures, intended to analyze the user behavior of residents, must be carried out during everyday life while minimizing disturbance to the occupants. In this respect, the miniaturized design of these compact data recording devices is particularly beneficial as they can be placed virtually anywhere while remaining inconspicuous.

Data Loggers Aid Accurate Diagnostics

In the experience of Bau-& Energieberatung Reto Niedermann GmbH, moisture damage analyses would not be possible at all without these small data loggers. After all, determining whether the user behavior is responsible for the damage to the building can only be done by means of long-term measurements of the indoor climate values. In the specific case, the temperature and humidity data of the outdoor and room air is recorded, as well as the acceleration values in the interior, in order to ascertain whether the data logger was moved to a different location by the user during the measurement period. Depending on the premises, the loggers are either positioned free-standing or attached with Velcro or adhesive tape. Then, for approximately two to four weeks, the loggers remain in the measuring sites of the building to be investigated. Upon completion of the series of measurements, the experts download the recorded data and, using the MSR PC software, are able to determine the exact indoor climate data at any point in time and draw the relevant conclusions, which provide the basis for the required proposals for remedial action. As the company has realized, detailed moisture damage analyses in such an accurate manner have only become possible by using these loggers. The examinations undertaken based on this logger data carry more weight due to the underlying measuring accuracy and are more meaningful than previously conducted examinations using traditional measurement tools. Furthermore, by using the software, examinations can be documented optimally, which, for instance, is of fundamental importance when preparing surveyors’ reports.

All in all, these miniature data loggers can contribute significantly to conducting damage analyses relating to building physics in a quick, accurate, and cost-optimized manner. However, these loggers are also useful in numerous other areas of application, such as transportation, machine and system monitoring, aeronautics, automotive engineering, or security tasks, and they are extremely successfully employed by many companies in these fields.

CAS DataLoggers had a unique customer—a group of paranormal investigators going ghost hunting! The organization planned to use ghost-hunting equipment with extensive temperature monitoring to pinpoint the sudden chills which guests reported in certain rooms on their list of possibly haunted sites, including historically significant areas such as bedrooms, basements, and attics.

Keeping their modest budget in mind, the team began searching for a wireless temperature monitoring solution that would allow personnel to view readings in real-time to respond whenever the temperature suddenly dropped in certain regions. Team members also wanted a convenient means of gathering all the data without having to walk every inch of these multi-story locations.

Installation

The paranormal investigators installed a T&D RTR-500BC Wireless Data Logger Base Station and 5 RTR-501B Wireless Temperature Data Loggers throughout their first house under monitoring and also used a T&D RTR-500DC Wireless Data Logger Handheld Data Collector to check the remote units’ real-time readings. Each of the wireless data loggers measured and recorded temperature using an internal temperature sensor reading from -40°F to 176°F (-40°C to 80°C) at an average accuracy of ± 0.5°C. Featuring an LCD display and a water-resistant case to protect against leaky roofs and basements, each data logger measured the surrounding temperature in either Celsius or Fahrenheit onto a large 16,000-point memory.

The organization chose the optional wall mounts which let them place the units anywhere to identify possible temperature causes such as pipes, cracks, etc. Utilizing a low-energy consumption design, each data logger operated on a lithium battery with a life of about 10 months and which could be upgraded to last about 4 years of operation.

Usage

The team registered the RTR-500BC as a base unit and began downloading temperature data and current readings from the remote units stationed around the house. Whenever their preset upper or lower limits were exceeded, a warning report email was immediately sent out to all four of the members’ email addresses. Frequent temperature drops were soon associated with certain areas, which were recorded and stored for future investigation. Free software was also included with the base stations for automated download and real-time monitoring as well as email alarm management.

Using the handheld data collector, the team viewed all the remote units’ real-time data from 500 ft. away unobstructed–this ability to react instantly to a sudden temperature drop or sighting was crucial to the project. The collector monitored and graphed all of the house’s temperature data without the need for a computer. In this way, the team wirelessly gathered the data at set intervals to monitor current readings and status from each of the remote units without anyone having to get up and walk around the house. The data collector also eliminated the need for any lengthy setup time such as having to create a network environment or install any wiring. Additionally, the collector’s LCD backlit display allowed users to read the data even in the dark, which was especially useful during all-night stakeouts.

Benefits

The team’s ghost-hunting project gained an effective ghost-hunting equipment solution by installing the T&D wireless temperature monitoring system. Using the handheld data collector, the team was able to instantly check the temperatures anywhere in the house instead of having to walk upstairs every time a reading changed. Together these wireless devices formed a wide-ranging and cost-effective solution for this unique temperature monitoring job, and the dataloggers’ compact and lightweight design meant they could be placed just about anywhere to zero in on the many strange readings encountered.

A common application for a data logger is to record load cell measurements for force or weight. A load cell uses one or more strain gauges packaged in a physical assembly that converts force into mechanical strain in a known, linear way. From the perspective of the data logger, capturing data from a load cell is simply a strain gauge or Wheatstone bridge measurement.

At a fundamental level, measuring a strain gauge is a resistance measurement, but the change is very small, typically on the order of a few hundred or thousand parts per million (PPM). Most load cells are configured with four strain gauges, one on each arm of the bridge, to improve measurement sensitivity.

Measurement Setup

A Wheatstone bridge consists of four strain gauges arranged as shown in Figure 1 below:

Figure 1. Wheatstone Bridge Diagram

Bridges are designed such that, with no load applied, the ratios R_1/R_4 and R_2/R_3 are equal, resulting in a zero output voltage (Vout). A small change to one of the resistances will then cause a corresponding change to Vout, which can be accurately measured using the data logger.

Strain gauges are what are known as ratiometric devices, which means that the output voltage is proportional to both the applied load and the excitation voltage. The output of a load cell (bridge) is usually given by the manufacturer in mV/V, which is the output voltage over the excitation voltage at the rated load. For example, a 1000-pound load cell might be specified as 2mV/V. This means that if you apply an excitation voltage of 5.0V and a load of 1000 pounds, the output would be: (2mV/V)*5.0V=10textmV

dataTaker data loggers have a built-in channel type for strain gauge measurements called a bridge measurement. Because this involves measuring resistance, some form of excitation is required. The dataTaker can be programmed for either voltage excitation (using an onboard or external source) or current excitation (using its internal source).

Voltage excitation is the most common method for strain gauges, but it requires accurate measurement of the excitation voltage value to get accurate results. Additionally, voltage excitation is not ideal for applications where the datalogger is separated from the load cell by long cables. Even though the current associated with the excitation is small, the resistance of long runs of cable will result in a voltage drop causing a loss of accuracy unless a six-wire configuration is used to allow remote sensing of the excitation voltage directly at the load cell. Current excitation is better for long cables because knowing the excitation current and strain gauge resistance allows you to accurately calculate the excitation voltage, although interpreting or scaling the data is slightly more complex.

The dataTaker’s default output for bridge measurements is in PPM, which is the output voltage of the bridge divided by the excitation voltage, multiplied by 10E6. In the example above with the 1000-pound load, the data logger would return: (10mV/5.0V) *1.0E6 = (0.01V/5.0V) * 1.0E6=2000PPM

There are two important considerations for bridge measurements:

• Zero-Load Offset: The output voltage (Vout) at no load is usually not exactly 0 volts. This is due to residual stress in the load cell and slight resistance mismatches between the four strain gauges. If the load cell will be used in a fixed application where the zero-load output is not expected to change, this offset can be entered as the channel factor in the measurement setup. However, if the load cell is used in a scale, the program will need the ability to capture the current value and then use it in a tare calculation.
• Calibration: The output is typically not exactly n.000mV/V but may vary slightly from unit to unit due to manufacturing tolerances. While it is possible to use the reported output coefficient, it is best to calibrate the system using a known load. Similar to the zero offset, you can take a known load measurement and then set up the math via scaling or use the logger’s calculation capabilities to provide a calibrated output.

Example

The example below shows how to set up a load cell using the dEX 2.0 programming software for the dataTaker with the built-in bridge channel type:

In this example, we are using voltage excitation with the logger’s built-in voltage source. To improve measurement accuracy, the data logger will internally perform a second measurement of the actual excitation voltage applied to the bridge and use this value in the final calculation. As mentioned before, the bridge measurement will return the result in PPM by default.

Figure 2. Bridge Measurement Configuration

To convert this value to a calibrated value in pounds, the data logger provides a built-in scaling function.

To use this scaling function, follow these steps:

1. 1. Take a measurement with zero load applied and record the value.
2. 2. Take a second measurement using a known load and record both the known load and the measured value.

In this example, a measurement of zero load returned -1.2 PPM, and applying a 500-pound load returned 501.5 PPM. These values are entered in the Span configuration as shown below, where “Measured” is the result returned by the datalogger and “Physical” is the actual value applied to the load cell.

Figure 3. Span Configuration

Summary

Measurement of load cells, which employ strain gauges in a Wheatstone bridge, is a common datalogging application. The dataTaker dataloggers provide a built-in channel type along with voltage or current excitation to capture data from a load cell. Accommodating the zero-load offset and small changes in output calibration can be easily accomplished using the built-in scaling and calculation capabilities of the logger to simplify measurement setup and obtain accurate results.

How to Best Protect Your Vaccines and Temperature-Sensitive Products

Maintaining accurate temperature monitoring and alarm generation in medical refrigerators and freezers is crucial for ensuring product safety, particularly in the context of vaccine storage, blood and tissue preservation, and other pharmaceutical applications. While the Centers for Disease Control (CDC) provides general guidelines for temperature monitoring, there are several areas that lack specific recommendations such as the type of temperature buffers to use with probes. To address this gap, CAS DataLoggers conducted a comprehensive study to evaluate the various parts of the monitoring system including elements such as the effectiveness of different types of thermal buffers. The findings revealed that using a temperature buffer, such as a glycol bottle or nylon block, significantly improves the accuracy of temperature readings and reduces nuisance alarms caused by door openings and compressor cycling.

Here are seven key recommendations for effective temperature monitoring in medical refrigerators and freezers:

1. 1. Utilize temperature data loggers: Data loggers provide an accurate record of temperature history, allowing for better monitoring and analysis of product temperatures. They can also be configured to send real-time alerts in case of temperature excursions.
   2. Use temperature buffers on all probes: Temperature buffers slow the probe’s response rate, making it more closely reflect the actual temperature of the stored product. Glycol bottles are particularly effective in both refrigerators. Select a buffer type appropriate for the usage temperature – glycol bottles for temperatures above approximately -10°C, and nylon blocks for temperatures below this point.

1. Position probes correctly: Place probes away from the evaporator coil or airstream of the coil fan to avoid fluctuations caused by compressor cycling. Avoid using dormitory or bar-style combination fridge/freezer units for medical storage as they tend to exhibit larger temperature swings than industrial/commercial units.
2. Fill combination refrigerator/freezer units with water bottles: This helps regulate temperature and prevent freezing or excessive cooling of products.
3. Monitor compressor cycling: Data loggers can display temperature graphs to visualize compressor cycling patterns. This information can be used to identify and control temperature fluctuations.
4. Calibrate probes to NIST traceable standards when necessary: NIST calibration ensures the accuracy of probe readings and is often required for regulatory compliance and high-precision applications.
5. Consider using CAS DataLoggers’ Accsense Pro medical monitoring systems: Accsense Pro systems are widely used by healthcare institutions and have earned the Joint Commission’s Gold Seal of Approval.

By adhering to these best practices, healthcare facilities can safeguard their valuable inventory, maintain regulatory compliance, and ensure the integrity of their medical products.

Previously, data loggers were primarily used in the food processing industry to monitor environmental conditions in warehouses, wine cellars, or during the transportation of foodstuffs. However, in this application, “Pures” grape juice cuvée from Reh Kendermann winery in Bingen am Rhein saw data loggers used in a completely different way. During the development of “Pures,” a white carbonated grape beverage, MSR145 data loggers were utilized to capture data inside a Champagne bottle as it was processed. These small data loggers, equipped with temperature and pressure sensors, supported product development and reliably recorded data on the sparkling wine bottles.

Measurement “In Vivo”

During the manufacture of the grape juice cuvée, the grape juice is carbonated and heat-treated. The primary factor affecting quality at this stage is pasteurization, an issue Johannes Grobeis, technical director at Reh Kendermann, handled with particular care. “Maintaining timing and temperature was very important to me. Low temperatures carry the risk of impairing product preservation, while temperatures that are too high can cause the caps to burst.” To obtain exact results, Johannes Grobeis wanted to place a data logger inside the bottle and then pasteurize the device along with the grape juice to record the critical parameters “in vivo.”

Since the logger had to fit through the neck of the bottle, its diameter could not exceed the bottle’s opening. At just 18.5 mm (3/4”) wide, the logger fits perfectly through the narrow opening.

Using the logger “in vivo” presented a range of challenges for the measuring device. The data logger not only had to be absolutely watertight, but it also needed to withstand temperatures of 72°C (160°F) and pressures of over 10 bar (145 PSI) during the development phase. The MSR145 mini data logger fulfilled these requirements. “Thanks to our special manufacturing procedures, we can insert-mold the logger, which is already designed to be watertight, inside a silicon sleeve with absolutely no bubbles. During hardening, the silicon becomes fully cured, making the device 100 percent watertight,” according to Wendelin Egli, CEO of MSR Electronics.

Benefits of the MSR145

“Based on the measurement results, we were able to verify and standardize the critical process parameters relating to process engineering and product safety within the shortest possible time and with minimum testing requirements,” Johannes Grobeis explains. “Because we had the ability to record data under real-time conditions, we only needed two large-scale tests before Pures was ready for the market.” For Johannes Grobeis, using the data logger was beneficial in every respect: “Using the ‘measuring probe’ not only saved us a huge amount of time, but we also obtained recordings made in the bottle under real-time conditions. With traditional systems that are incorporated into the bottle closure and actuated from outside, real-time measurements are not possible.”

Introduction: The Unseen Dangers In Art Transportation

The world’s priceless art is constantly on the move, traveling between museums, galleries, and private collections. According to recent data, the estimated value of art transported globally each year is around $68 billion! During these journeys, paintings face numerous risks, particularly from shocks and vibrations. Rough handling at museums, bumpy truck rides, and airport cargo operations can all lead to damage, potentially resulting in significant financial loss and the irreplaceable loss of cultural heritage. For example, a ceramic bust created by Picasso’s shattered while being transported in a shipping case. Imagine the cost of a damaged masterpiece, not just in monetary terms, but in the loss of history. This project aimed to redefine how we understand and mitigate these risks, leading to improved packaging and safer transport.

The Research Project: A Collaborative Approach

The research initiative (www.gemaeldetransport.ch) was undertaken to develop a new system for classifying the shocks and vibrations that occur during artwork transport. By understanding these forces, we can better assess risks and establish tolerances for preventive measures. The project combined laboratory simulations with real-world transport measurements to evaluate existing packaging and develop future solutions.

This interdisciplinary team included experts from the Department of Conservation and Restoration (KuR) at the University of Bern/Bern University of the Arts (HKB) and the Institute for Mechatronic Systems (ifms) at the Bern University of Applied Sciences in Burgdorf, Switzerland. The project was supported by four business partners: a Swiss insurance company and the four leading Swiss art transportation firms plus specialists from various Swiss museums as partners that were able to contribute practical experience in this area.

Monitoring Real-World Shipments: Understanding Forces At Play

Initially, a custom-built measurement system was used to record shocks and vibrations inside packing crates. While this highly accurate system allowed measurements to be carried at a measurement rate of up to 2,000Hz over a period of several days, this system was expensive, complex, and cumbersome. It was impossible to pack this system into the crate along with the painting – instead it had to be packaged in a separate box that is connected via cables to the acceleration sensors mounted inside the painting’s crate.

Figure 1. MSR165 Mounted On A Painting Frame

A more practical solution was found in the MSR165 data logger. This compact device, equipped with an internal tri-axial acceleration sensor, humidity sensor, and a 4 GB micro SD memory card, allows for continuous measurements up to 3 days. Its small size and integrated sensors enable it to be mounted directly to a painting’s frame or inside a crate, eliminating the need for bulky equipment and cables.

While the MSR165 has only been used to measure the shocks and vibrations acting on the frame of a painting or on the internal wall of a packing case, its four additional analogue inputs allow additional uniaxial acceleration sensors to be connected so that vibrations in the fabric supporting the painting can also be measured.

The MSR165 recorded data continuously at a sample rate of 1,600 Hz, allowing researchers to capture every shock and vibration event. The data was then downloaded and analyzed using software MATLAB to determine maximum values, RMS levels (a measure of average vibration intensity), and dominant frequencies.

Figure 2. Vibration Level Along 3 Axes

In addition to mechanical stresses, climatic variations can also damage artwork. The MSR165’s humidity sensor allows for the simultaneous monitoring of temperature and humidity, providing a comprehensive view of the environmental conditions during transit.

Evaluating & Improving Packaging

The type of packaging used for artwork varies depending on the painting, route, and transport method. From simple bubble wrap to elaborate double isolated packing crates, the goal is to minimize both continuous vibration and shock events during transport.

To compare the effectiveness of different packaging systems used by different shipping companies, test journeys were conducted using trucks with air suspension. Up to 8 identical test paintings, each packaged differently, were subjected to the same stresses. MSR165 data loggers attached to the frame of each test painting recorded the vibrations experienced during the journey over highways, motorways and city traffic. At the same time, the custom measurement system recorded vibrations at the truck’s floor and walls.

The data collected from these tests allowed researchers to assess the pros and cons of various packaging methods and develop strategies for optimization. By analyzing the vibration data, they could see how well each packaging system protects the art. The results of the research project, which can be viewed at www.gemaeldetransport.ch, highlight the pros and cons of the different packaging methods and offer suggestions for optimizing them.

Key Findings & Future Directions

The use of MSR165 data loggers has proven to be a valuable tool for understanding and mitigating the risks associated with artwork transport. By collecting detailed shock and vibration data, we can develop improved packaging solutions that minimize damage and ensure the safe arrival of priceless art. We encourage museums and transport companies to consider the benefits of using data loggers like the MSR165 to monitor high value shipments and enable data-driven packaging improvements. By working together, we can ensure the safe transport of the world’s art treasures for generations to come.

CAS DataLoggers played a pivotal role in providing the structural monitoring solution for the Los Angeles County Museum of Art (LACMA) as it embarked on its conservation project for the Watts Towers, a renowned monument of regional folk art. Constructed by Italian immigrant Simon Rodia between 1921 and 1954, the Towers stand as an iconic testament to Los Angeles’ cultural heritage. The tallest structure reaches nearly 100 feet, with 17 towers crafted by hand using steel rods, wire mesh, and cement, adorned with mosaics made of ceramics, shells, bottles, and tiles. These unique pieces reflect the contributions of Rodia’s community, who helped him gather materials over the years. Named a National Historic Landmark in 1990, the Watts Towers, also called ‘Nuestro Pueblo,’ have become an enduring symbol of artistic ingenuity, standing proudly in the city even after Rodia’s departure in 1955.

Developing A New Preservation Plan

In October 2010, LACMA contracted with the city’s Dept. of Cultural Affairs to preserve the towers by conducting daily maintenance on the site and by revising the 1983 Conservation Handbook to develop a new preservation plan. Over the past 40 years, workers have attempted to patch the towers’ cracks, but the damage kept reappearing. To effectively restore the Watts Towers, LACMA’s Conservation Dept. needed to see how these structures were behaving under several environmental influences.

Dr. Charlotte Eng works as part of LACMA’s Conservation Center and has helped to restore much of the Museum’s collection over several years. As a Conservation Scientist and a Doctor of Materials Sciences and Engineering, Dr. Eng specializes in identifying needed materials and repairs to many different types of artwork. She and the rest of the team have worked to restore and protect one of LA’s most impressive and accessible art installations.

Analysis to Develop Restoration Efforts

The LACMA team’s efforts focused on finding and monitoring the movement of cracks in the site’s cement covering and fissures. To do this, the Department needed to capture movement or displacement data to see where the fissures were opening and to what extent. The conservation team then repaired the cracks using a custom repair material consisting of elastomeric crack fillers and polymer-amended mortars. This will ensure that the repaired areas move by the rest of the structure to preserve its overall integrity.

LACMA also worked with UCLA’s Department of Engineering to record a combination of structural response and environmental data that will show where the damage to the structure is originating, which will guide all future efforts. Macroscopic monitoring techniques have already been undertaken on the site and structure, including telephoto photography, radiography, and the use of high-magnification spotting scopes. Dr. Eng explains, “The Towers have also been laser-scanned and analyzed with ground-penetrating radar sweeps to show us the ground’s stability.”

Additionally, the Watts Towers are affected by many other factors including the day’s heat, wind speed, seismic activity, and more. For example, tilt meters have confirmed that the top of the main tower moves slightly as the day progresses and begins moving back again in the evening. This produces slight movements causing stresses that crack the concrete and cause other deterioration such as loss of the Towers’ ornamentation. To combat this, the team has to continually monitor the movement of the Towers and their foundations.

LACMA’s project supervisor and Senior Conservation Scientist Dr. Frank Preusser has over 40 years of experience working with prestigious sites including the Egyptian pyramids, the Getty Museum, and museum-based work around the world. He and the department searched for new damage and areas where the Towers were losing their ornamentation. This work required a high-accuracy data logger that could connect with the project’s specific type of displacement sensors. With this in mind, Dr. Eng contacted CAS DataLoggers to find a portable device that allows users a quick way to get the data: “As a guide, we looked at monitoring projects conducted by other institutions such as UCLA which have successfully used a similar setup.”

System Installation:

LACMA’s Conservation Department has implemented a dataTaker DT80 Intelligent Universal Input Data Logger, provided by CAS DataLoggers, to assess the structural condition of the Watts Towers during its ongoing conservation efforts. This advanced system continuously monitors the towers, with the team strategically placing the portable data logger around the base of the central tower to take critical readings. As the inspection uncovers cracks, particularly around the base where the majority of the structure’s weight is concentrated, the DT80 will be relocated and mounted to a support structure above ground level. Notably, cracks are less common near the top of the towers, where the concrete and rebar are thinner and more flexible. Designed for durability, the DT80’s removable screw terminals ensure a secure installation in this outdoor environment, while its plastic cover safeguards the device from rain. Thanks to its rugged construction, the dataTaker DT80 can be left outdoors without concern, making it an ideal tool for monitoring the towers despite any unpredictable changes in LA’s weather.

The team is currently using a pair of  Firstmark Series 150 Subminiature Position Transducers to monitor the movement of the cracks, relocating the sensors around the base of the central tower’s structure to find which cracks are moving through trial and error. The DT80’s built-in excitation sources are used to power the sensors. These transducers use a measuring cable affixed to an attached shaft and spring loaded spool that is attached to a rotary potentiometer. With the sensor attached on one side of the crack and the end of the cable on the other side, as the crack opens or closes the movement of the string causes the potentiometer to rotate changing the resistance measured by the data logger.

This way, the sensor translates a crack’s linear movement into a variable resistance which the dataTaker reads and records. Once a new crack is found, each sensor’s cable measures its linear position to see how much and how quickly it’s opening and closing. Users set up the dataTaker to take a reading from each sensor once every 15 minutes as suggested by CAS DataLoggers. With the ability to measure up to 15 analog inputs, an 18-bit measurement resolution, and digital, counter, and serial sensor inputs, the dataTaker data loggers can read data from most sensors allowing the team to add sensors to capture other data like temperature, humidity, wind speed and wind direction. Add on CEM20 channel expansion modules allows the DT80 to measure up to 100 analog input channels. An internal lead acid battery allows the logger to run for an extended period of time without external power. In this case, with a 15-minute sampling interval, the logger could run for over a month on battery power allowing the team to easily collect survey data without the need for an external power source.

Data Collection:

The DT80 data logger stores up to 10 million data points in its user-defined memory so that users can log as much or as little as needed, with the ability to independently control schedule size and mode. The logger’s flexible COM drive from the datalogger’s USB port quickly collects the data. Once a month, a team member climbs up a short ladder to pull out the Flash drive, puts it in a laptop to download the data, and replaces it.

Dr. Eng explains, “We’ve retrieved the data and now we’re checking it for evidence of any seismic disturbances since earthquakes are frequent in this area. Other influences may result in extreme data, such as the ‘Santa Anas,’ the hot winds blowing in from the desert at 50 to 60 miles per hour, so we’re looking for those indications too.”

Analysis Software:

In addition, dataTaker’s dEX2 graphical interface software is provided with the data logger. This user-friendly, Windows Explorer-style software enables quick setup and configuration, suitable for both novice and advanced users. The software runs on a standard Windows PC and communicates with the logger via a USB or Ethernet connection. The dEX2 software provides a simple dashboard with displays of real-time measured values plus trend charts that could show the movement of the cracks over days or weeks.

Benefits:

The dataTaker and string potentiometers are well within the Conservation Department’s budget, the real advantage being that the measurements and software are packaged in a single system. Dr. Eng sums up why LACMA chose dataTaker for their application: “We had several needs for this phase of the project: our system had to be portable, it had to be small, and it had to last more than a week or two. This system runs on its own out there indefinitely, it’s easy for us to get the data, and its compact size and removable screw terminal connections make it easy to install and connect the sensors.”

She continued, “We looked at similar projects using data loggers, but they had large and heavy batteries or they had to be hardwired first. We knew we wanted something standalone that would save us all that work; the USB retrieval is very handy and can be done by anyone at any time. Someone just brings a laptop and collects the data that way.” From there, the data can be analyzed in detail from an office PC.

The team can easily put the versatile dataTaker to work on other projects, using its universal inputs to log other values. “We can also use it for our strain gauge sensors. The logger we currently use to take strain gauge data is much bigger, about 12 x 12 inches and 3 inches thick, so it will be much easier to just use the dataTaker for that application too.”

As conservator of the Watts Towers, LACMA’s ongoing restoration work with this new data collection technique is helping to revolutionize how art installations are restored and preserved. Thanks to the Conservation Department’s efforts, the near century-old Watts Towers will continue to amaze visitors to Los Angeles for decades to come.
