K-IEPE
INF2213
Our K-IEPE module is designed to connect IEPE sensors to a K-Box or K-AN8 voltage measurement device that normally cannot support IEPE sensors.
The powered K-IEPE module simply enables IEPE sensors to be connected via the BNC terminals and will output the signal voltages to the analog measurement device.
Calibration and sampling rates can be configured using the freely distributed K-Cal software.
