Industrial IEPE Piezoelectric Accelerometer


The iQunet IEPE Piezoelectric Accelerometer is a device that monitors asset health of rotating equipment which fits well in the predictive maintenance and asset reliability strategy.


The iQunet IEPE Annular Shear Piezoelectric Accelerometer is a compact 4mA powered device that measures vibration data. The sensor is powered with a constant 4mA current supply (2 to 10mA DC). The accelerometer collects single axis analog time series vibration data using the industry standard ICP/ IEPE /LIVM 2-wire voltage transmission technique. The Piezoelectric Accelerometer can be integrated in the iQunet system via the iQunet IEPE Vibration Module for the iQunet Wireless Sensor Bridge where the analog signal is digitalized and prepared for wireless transfer to the iQunet Server. The digital sensor data can then be collected on the iQunet Server and sensor parameters such as sampling rate, number of samples, dynamic range, automatic measurement interval, etc. can be set remotely.


The sensor makes a network to the central Base Station node via the Repeater module build in to the Wireless Sensor Bridge. Sensor data is visualized in the iQunet Sensor Dashboard on the iQunet Data Server, offering time series in acceleration (g) and velocity (mm/s), spectrum graphs in (g) and (mm/s) including waterfall plots, RMS trend values and graphs in (g) and (mm/s), crest factor, peak values, etc.


Used in: condition monitoring of bearings, misalignment, unbalance, … of rotating equipment in harsh industrial environments
