Vibrating Fork Type Level Switch

V. Automat Level Sensors the complete system consists of the sensing probe of vibrating fork and the electronic switching unit. Features:- • Fast and easy installation • No effect of electrical properties of the Service material. • Suitable for the highly dusty environment. • Suitable for grain size up to 20 mm.

The electronically stimulated fork vibrates at its mechanically resonance frequency of abount 125Hz/400 Hz when the fork is free of the service material. The resonance is caused by the piezoelectric crystals. One of the piezo crystals produces a small voltage which is transmitted to the switching amplifier. If the fork is covered by the bulk material, a damping effect is produced and the piezo crystal does not produce the voltage and the amplifier will switch and a corresponding signal output is actuated. The vibration of the fork has self-cleaning properties.
