Wired Vibration Transmitter (With A Dynamic Output)

A casing-mounted, vibration sensor with a dynamic signal output commonly used for industrial machinery monitoring. An Integral Electronics Piezoelectric (IEPE) accelerometer incorporates a built-in preamplifier, which transforms the high impedance charge output of a piezoelectric ceramic into a low impedance voltage signal that can be transmitted over longer distances. The output signal from the accelerometer is a voltage signal that is superimposed onto the same line on which constant current is supplied. A coaxial cable is typically used between the accelerometer and signal conditioner or data acquisition system, although most industrial-grade accelerometers use shielded, twisted pair cables.
