PCB Piezotronics IMI SENSORS EXM641B01 Installation And Operating Manual page 13

Intrinsically-safe vibration sensor, 4 to 20 ma output, 0 to 1.0 in/sec rms, 10 to 1k hz, top exit, 2-pin conn

TO Option

The TO (Temperature Output) option includes an additional independent 4-20mA output for temperature

measurement. The temperature range is from -40°C to 125°C with an overall accuracy of ±5%FSO. The

imbedded temperature sensor monitors the environment internal to the sensor housing and is situated at

approximately mid level.

Note:

- The same power supply can be used for both 4-20mA loops. Connect both positive terminals directly to the

power supply, then use the negative terminals for independent process loops.
