TM0793V-K piezoelectric crystal type speed sensor. The velocity sensor and kit includes the velocity probe and a 5 meter cable.The TM0793V-K can be connected directly to PVTVM monitoring instruments such as the DTM Digital Transmitter Meter, TR Transmitter, and PT580 Digital Vibration Switch. It is used to measure enclosure vibration and output a velocity or displacement signal.
