Explosion proof typed tuning fork level switch, d ii ct6
Fundamental principles
The su-yc vibrating probe level switch/liquid level control switch is a kind of universal liquid level switch, which is brought to its resonance frequency by means of piezoelectric crystals drive. If the tuning fork is covered by liquid or solidity, this frequency will change. The electronics of the su-yc monitor the resonance frequency and then output a switching value, in this way, to alarm and control the liquid level.
The structure and characteristics of tuning fork liquid level switch make it can replace any level switch of other principles, and can be widely used in building materials, petroleum, chemical industry, light industry, metallurgy field to alarm or control the height of liquid level for their lower and upper limit.
