PCB Piezotronics 4-20 MA Transmitter

The Model 655A9X & 656A9X Series Industrial 4-20mA Sensors combine the capabilities of a piezoelectric vibration sensor and a 4-20mA vibration transmitter. The sensor outputs a 4-20mA signal that is proportional to the overall velocity or acceleration of the machinery. Ideal for monitoring the vibration of process equipment such as fans, motors, and pumps, the output of the sensor is used for process control or predictive maintenance. It has an imbedded piezoelectric accelerometer to improve accuracy and frequency response. Flexible design allows it to meet custom requirements.
