GCT220 type tuning fork switch

Product Features

Adopting a new type of piezoelectric crystal sensor with high sensitivity and reliability, modular electronic component design, small and compact structure,

Electronic switch output, all stainless steel casing; Suitable for most liquids, medium density, solid particle powders

The measurement is not affected by foam, pressure and eddy current.

Working principle

A pair of piezoelectric crystals installed on a metal tuning fork base, excited by voltage to oscillate with the fork at a certain resonance frequency

When the tested medium also comes into contact with the tuning fork, it changes the vibration frequency and amplitude of the tuning fork, which can be observed in highly integrated circuits

Detect amplification and convert it into high and low level off signal output.
