Explosion-proof tuning fork switch features description

Explosion-proof tuning fork switch features
Explosion-proof tuning fork switch Explosion-proof tuning fork switch is a general-purpose 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.

Explosion-proof tuning fork switch features

The explosion-proof tuning fork switch has strong adaptability, and the different electrical parameters and density of the tested materials have no influence on the measurement. It is maintenance-free. Since the detection process of the explosion-proof tuning fork switch is completed by electronic circuits and there are no moving parts, maintenance is not required once installed and put into operation. No adjustment is required. Since the detection of the explosion-proof tuning fork switch is not affected by the electrical parameters and density of the measured medium, no on-site adjustment is required regardless of the liquid to be measured. Explosion-proof tuning fork switches have no effect on the detection of harsh conditions such as fouling, agitation, turbulence, air bubbles, vibration, medium viscosity, high temperature and high pressure.
