The explosion-proof tuning fork switch is a universal tuning fork switch.
The tuning fork of the explosion-proof tuning fork switch is excited by the piezoelectric crystal to generate vibration. When the tuning fork is immersed by liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switching quantity.
The explosion-proof tuning fork switch is not affected by the dielectric parameters of the medium, as well as turbulence, agitation, air bubbles, vibration and other factors. It has no moving parts, so it requires no maintenance and adjustment. It is an ideal choice for level switches in complex working conditions.
