4-20 mA piezoelectric vibration sensors are design to monitor the vibration in harsh industrial environment. It uses the industry standard 4-20 mA loop that interfaces directly with PLC, DCS and 4-20mA monitor. VibraSens transmitters are using state of the art annular shear design.
Note about obsolete compression design transmitter.
Compression design 4-20 mA velocity vibration transmitter are limited to a low frequency = 10Hz.
It means that you will not able to monitor (velocity parameter) machine runing below 500 RPM.
Annular shear vibration transmitter is the only design able to measure machine down to 150 RPM.
Compression design vibration transmitters are also more sensitive to cable motion, transverse vibration and electronic saturation at high frequency.
