Explosion-proof tuning fork level switch is also often called tuning fork level meter or tuning fork level controller, mainly because tuning fork level meter in different stages of industrial production, the actual key role is different, people are used to call out a lot of different names. The tuning fork level switch is a kind of level switch, which mainly uses the tuning fork resonance principle to measure the state of the level, and the design of the fork body and its inherent vibration characteristics can ensure the automatic cleaning function of the tuning fork and prevent the hanging material.

Explosion-proof tuning fork level switch is to use the media damping effect of vibration of a tuning fork and design of the principle of piezoelectric effect, the detection of material (liquid) sensing part is composed of a tuning fork, on its own has a fixed vibration frequency and amplitude of vibration, when there is medium damping effect of tuning fork, fork stop vibration, driven by control circuit relay signal switch. The product can adapt to the harsh working conditions of the site, reliable work, is the material (liquid) level switch instrument used for a wide range of products

Product features

1. Strong adaptability: different electrical parameters and density of the measured medium have no effect on the measurement. Scaling, agitation, turbulence, bubble, vibration, medium viscosity, high temperature, high pressure and other adverse conditions have no effect on the detection;

2, no need to adjust: because the tuning fork level switch detection is not affected by the electric parameters and density of the measured medium, so no matter what medium is measured, there is no need for on-site adjustment;

3, free from maintenance: because the tuning fork level switch detection process is completed by the electronic circuit, no moving parts, so once the installation is applied, there is no need for maintenance.
