722 Ultrasonic Switch
Brand: SOR IncThe 722 ultrasonic switch is an advanced dual-point device designed to meet your needs for sump/ pump control.
In addition to the features of the 712, the 722 includes a “Sensor Monitor.” This circuit continuously tests the functionality of the electronics and sensor (both gaps). The “Sensor Monitor Relay” de-energizes if a fault is detected.
It is available integral or remote mounted and comes standard with field-selectable failsafe and time delay.
Features- No calibration required
- Continuous self-test (sensor monitor) verifies operation of the unit
- FM Approved or CSA Certified for hazardous locations
- Field-selectable failsafe
- On/Off time delay is standard
- Rostechnadzor (RTN) standard certificate
