With its Expert Vibro EV-4 Data Acquisition System device, Delphin has successfully combined the processing of complex functions with high levels of flexibility in a user-friendly system. Vibration measurement systems can now be used where they had previously been economically infeasible. The device is equipped with a high-powered, dual-core FPGA processor based on ARM technology giving users ample reserves of processing power.

Users are able to switch between voltage measurement, IEPE, or shaft vibration sensors. Integrated comparators and digital inputs allow flexible triggering. Measurement data is monitored “on the fly” with digital outputs being switched within msecs in the event of limit value violations.

Vibrations deliver information on the condition of bearings, shafts, and machinery and generally have a major effect on levels of quality in production processes. They should, therefore, be continuously acquired, intelligently evaluated, and condensed into meaningful data for monitoring. In critical situations, machinery needs to be shut down within milliseconds.

The Delphin Expert Vibro EV-4 combines the requirements and functioning of modern vibration measurement systems into a highly compact device. Other systems usually require multiple pieces of equipments. Vibration measurement is made easy with Expert Vibro. System installation and familiarization are short so that users can quickly start processing their data.

Expert Vibro provides users with analysis and monitoring functions, intelligent signal processing, an independent data storage capability, and versatile Fieldbus connections – all in a single device. Right from the outset, users save costs and avoid troublesome interface problems.

Of special benefit is the modular system for signal processing with a range of preprocessing functions. Filters, such as high, low, or bandpass with rectifiers, integrators, differentiators or decimators can be selected to make up a preprocessing sequence. Multiple preprocessing sequences are able to run in parallel in order to evaluate an input signal. This gives users an especially high level of flexibility.

Non-periodic signals, such as in fault diagnostics, can be analyzed precisely using Expert Vibro. In continuous sampling mode, even the smallest of irregularities are recorded. Expert Vibro measures, monitors, and records fully independently. Expert Vibro is equipped with its own internal data storage capability making it especially reliable and secure.
