Vibration transmitter – iT150

Wilcoxon’s 4-20 mA vibration transmitter module, the iT150, provides an easy means to connect a standard IEPE vibration sensor to a PLC, DCS or SCADA system. The transmitter's input provides power to and measures the signal from either an accelerometer, piezovelocity sensor or dual (vibration and temperature) output sensor.

The input circuitry has a wide frequency response, capable of measuring signals between 0.2 Hz and 20,000 Hz, as well as a True Peak detection mode out to 25 kHz.
