IMI 4-20 mA Output Velocity Sensor 640B02
4-20 mA Output Velocity Sensor
Industrial vibration sensor, 4 to 20 mA output, 0 to 2 in/sec pk, 3 to 1k Hz, top exit, 2-pin conn.
Measurement Range: 0.0 to 2 in/sec pk (0.0 to 50.8 mm/s pk)
Output: 4-20 mA
Frequency Range: (±10%) 180 to 60000 cpm (3 to 1000 Hz)
The Model 640 B Series Industrial 4-20 mA 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 predicative maintenance. There are many options in this series. Please call for details.
