Description

technical field [0001] The invention relates to the technical field of explosion-proof tuning fork liquid level detection, in particular to an explosion-proof tuning fork liquid level detection device. Background technique [0002] 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 in liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit and outputs a switching value. The explosion-proof tuning fork liquid level detection switch device uses the tuning fork It is designed based on the principle that the frequency between the forks changes with different media. When the tuning fork changes from a dry state to a wet state, or from a wet state to a dry state, this change causes a frequency change, which can be detected by a wet or dry electric sensor , through the intelligent electronic device into the corresponding switch...
