Piezoelectric velocity sensor

Piezocelocity rransducers (PVT™) are solid state piezoelectric velocity measurement devices. Many vibration analysts prefer to examine vibration signals in terms of velocity (inches per second or ips) to amplify the signal of interest. PVT™ sensors inherently decrease high frequency signals allowing better measurement of low frequency vibration. PVT™ sensors are essentially accelerometers with an internal integration circuit which will produce an output relative to velocity.
