Vibrating Fork Level Switches For Liquids and Solids

Vibrating fork level switch consists of two forks or two arms which vibrate continuously because of their contact with piezo electric crystals. Hence the name vibrating fork. The tuning fork vibrates at its mechanical resonance frequency of about 1000 Hz. The frequency changes when the fork is covered by the medium. This change is detected by the integrated oscillator and converted into an output – Relay, PNP or analog.

The material could be a viscous liquid, slurry or even free flowing powders. (Contact our technical team to help you decide the type of fork to be used.)
