722 Ultrasonic Switch

Brand: SOR Inc

The 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
