Vibrating Fork Point Level Switch for Solids

Working Principle

trumenElectronics of LSV excites the piezo-electric-crystals inside the tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.

trumen Amplitudes of vibration are above threshold when tines are free to vibrate.

trumen When material touches the fork tines, vibration stops as resonance gets disturbed.

trumen Amplitudes of vibration, as sensed by electronics falls below the threshold strength, material presence is thus detected.
