It is a compact and easy-to-install switch suitable for the detection of a wide variety of liquids in tanks, containers, or pipelines.
The vibrating fork is attached to a housing containing a piezo crystal and sensing electronics. The fork vibrates in air at the resonant frequency of the piezo crystal. The vibration gets damped when the fork comes in contact with liquid, which is sensed by the electronics to provide a PNP switching output. This output can be used to operate a relay or as input to a PLC.
Flow / no flow of liquid in pipeline.
Overfill detection.
Leak detection.
High, low level alarm.
Pump dry run protection & pump control.
Suitable for oil, water, and similar liquids.
