Compact Vibrating Fork Type Liquid level switch is a simple, low cost, rugged point Level Switch designed for Level detection of liquids in a tank or vessel. This level switch can be used for detecting high, mid or low or for both level detection. The unit has integral electronics along with sensitivity adjustment and time delay feature, LED indication, fail safe logic etc.

Basically, the Liquid Vibrating fork type instruments are used for Level detection in Resins, water, oil, acids, chemicals etc. when the media/ liquid level reaches up to the Vibrating fork/ probe, The vibrations of the fork are damped because of the liquid in contact, and sensing signal reached to connected electronics circuitry and generates a switching signal to relay circuit integrated with timer functions. The fork vibrates at vibrating frequency of 350 Hz (±10Hz)
