The Echotel 961/962 series utilizes pulse wave technology to detect high or low level alarm(s)in a broad range of viscous to light liquids.
The Echotel 961 has a tip sensitive setpoint and is ideally used as high or low level alarm.
The Echotel 962 offers 2 setpoints on the same sensor. The unit is used for level alarm or pump control.
The Echotel 961/962 is equipped with advanced diagnostics that continuously check the sensor and electronics.The diagnostics also alarm for electrical noise interference from external sources.

Measurement Principle:
High frequency 2 MHz ultrasonic pulses are transmitted across a transducer gap in the presence of a liquid medium, but are attenuated when the gap is dry.
Features:
No calibration
Loop current or relay output
