Modes of Operation

Modes of operation include autonomous battery operation or power supply through the USB port for unit configuration. During battery-supplied operation, only the low-power microcontroller is awake. The microcontroller activates the modem during data transfer, as well as other subsystems for sampling and logging.

Data Acquisition

The sampling period and data send rate are user definable. Ultra-low power standby mode followed by frequent data recording and transmission can be selected to fit the application needs while maximizing the battery life.

SDI-12 Serial Bus

SDI-12 is an asynchronous, ASCII, serial communications protocol that was developed for intelligent sensor instruments that typically monitor environmental, structural engineering, and precision agriculture data. Communication is achieved by digital communications. The addressing system allows the data recorder to communicate with several microprocessor-based sensors over a single line. ADS-300 is compliant with the SDI-12 Standard Version 1.2 and supports extended commands for sensor configuration, in terminal mode. ADS-300 can collect data from several SDI-12 sensors for a total amount of 8 measurement channels.

RS-485, MODBUS

ADS-300 supports acquisition from sensors with RS-485 interface, using the popular MODBUS protocol (RTU & ASCII).

Transducer excitation

The unit provides multiple excitation options for measuring transducers. A user-adjustable 5V/12VDC excitation output is available for powering low-power external sensors.

Tilt Sensing

The unit has an optional accelerometer which is used for measuring angle declination.

Coulomb Meter

A user-enabled Coulomb Meter allows for the monitoring of the battery’s consumption.

Setup and Programming

The unit can be programmed locally through the serial by using simple ASCII configuration commands. The command set features commands for configuring scaling and timing parameters.

Enclosure

Plastic enclosure (IP66/68) for in- and outdoor use.

The ADS-410 allows periodic capture and data transmission of sensor data via the Itron network for advanced analysis and applications. It also provides immediate alarm messages and periodic health messages for verifying unit availability. A built-in continuous battery gauge monitors cumulative consumption to allow for notification when it’s time to replace the battery. Remote configuration of operation parameters is available as well as the ability to scale parameters and user-definable alarm limits.

The ADS-410 is designed to piggy-back onto an existing AMR network to allow for specialized applications including environmental monitoring, weather and flood monitoring, water resource management, leak detection, and other non-standard device monitoring.

Advanced design and technology plus 25 years of geotechnical expertise have produced the dataTaker DT80GW WiFi Geotechnical Data Logger – A versatile, powerful – yet low-power & cost-effective logger.

It supports vibrating wire and other geotechnical sensors such as Slope Indicator, RST Instruments, Geokon, Soil Instruments, Roctest, AGI – Applied Geomechanics Inc. DT80GW is also capable of testing sensor integrity through audible frequency

With temperature compensation (thermistor), 5 analog channels are capable of reading up to 5 vibrating wire sensors. If temperature compensation is not required this logger can read up to 15 vibrating wire sensors.

Further expansion up to 100 sensors (with temperature compensation) or 300 sensors(without temperature compensation) is possible.

Local Wireless Access

With wireless access, no need to have a physical connection to the logger. Send the program, view and download the data, or even modify your settings on a nearby PC or Tablet wirelessly either as a Master (Access Point mode) or Slave (Client).

Automatic Data Delivery

On Client mode, dataTaker can have access to a local router and if the router has internet access it can utilize the DT80GW’s automatic data delivery features to schedule your data to be automatically emailed to your inbox every day, week, month, or other time interval.

More sophisticated systems can make use of the automatic data delivery features to send logged data to an FTP server.

Superior Data Storage & Communications

With the standard unit able to store up to 10 million data points (expandable) you can log as much or as little as you need. Overwrite or stop logging once allocated memory is full, archive data on alarm event, copy to USB memory or transfer via FTP/ Email, the choice is yours.

Communications features include RS232, USB, and Ethernet, which connect to the DT80GW locally, remotely through a modem, or over the Internet.

Versatile Measurement

The DT80W WiFi Universal Input Data Logger allows you to connect an array of sensors through versatile analog and digital channels, high-speed counter inputs, phase encoder inputs, and programmable serial sensor channels.

Temperature, voltage, current, 4-20mA loops, resistance, bridges, strain gauges, frequency, digital, serial, and calculated measurements can all be scaled, logged, and returned in engineering units or within statistical reporting.

Set up sampling, logging, alarm, and control tasks to suit your requirements while interfaces for smart sensors, GPS, and other intelligent devices expand the dataTaker DT80W flexibility.

The Expert Logger 400 is Delphin‘s new generation of data loggers. It combines the latest communication technology with advanced measurement technology and is based on FPGA technology to make it especially powerful. It can process up to 16 analog input channels at both low and high rates of sampling. Measurement data can be accurately acquired, independently stored and transmitted to the internet or a PC for evaluation via USB, LAN, WLAN or LTE.

Operation Made Simple

Sensors are connected via plug-in screw terminals and a chart clearly shows how channels are arranged. Users always have a good overview of the channels despite their high density. Each set of four terminals can be configured as two differential inputs to measure voltage, currents, thermocouples, or to take measurements from a 4-wire RTD.

Configuration – Fast and Easy

The Expert Logger 400 is simple to configure from a PC. These settings remain stored within the Expert Logger even when disconnected from the power supply. The device settings can also be read out and stored on a PC and analyzed offline without the need for a connected Expert Logger. The offline configuration settings are then simply read into the device when connected. The software used for configuration is simple to operate to let users fully focus on their measurement tasks.

Intelligent Signal Processing

Signal processing using internal software channels significantly simplifies measurement tasks. Flexible calculation channels enable measurement data to undergo further computation and recording. Integrators directly calculate volumes or quantities from time-related measurement data such as mass and discharge flow rates. Limit values can monitor measurement data and be used to switch digital outputs or automatically send emails. Complex signal processing is possible using pulse counters, stop-clock functions, and operating-hours counter. Averages can be calculated and recorded as time-weighted or moving. The Expert Logger‘s software channels clearly set it apart from other loggers and make it very popular among users.

Applications

• Data logging
• Environmental measurement technology
• Product testing
• Measurement data diagnosis
• Lab data acquisition
• Trials and tests
• Energy optimization
