Vibrating Fork
Compact Size

The Nivelco NIVOSWITCH RL series of vibrating fork level switches are robust instruments designed low and medium viscosity liquids. Mounted on tanks, it can control filling / emptying, or give fail-safe alarm signals.

 

The operation principle is based on that the electronic circuit excites the vibration in the fork probe. When the medium reaches and covers the fork, the  vibration stops, when the medium leaves the fork, it returns to vibrate freely. The electronics senses the change of vibration and gives output signal after a selected delay.
