Anti-adhesion Tuning Fork Level Switch for Liquid and Solid Media
Product Description
YC series tuning fork level switch is a new type of level switch. It is designed and manufactured using the principle of tuning fork vibration. It is the base of the induction rod of the tuning fork level switch. The tuning fork is driven by the piezoelectric wafer, and the vibration signal is received by another piezoelectric wafer, so that the vibration signal can be circulated and the induction rod resonates. When the material contacts the sensor bar, the vibration signal gradually becomes smaller, and the control circuit outputs an electrical acceptance signal until the resonance stops.
Due to the natural principle that the sensitivity of the sensing rod gradually decreases from the front end to the rear seat, no error signal will be generated when the material in the tank and the barrel are stacked upwards, touching the base of the sensing rod (rear) or discharging.
The tuning fork generates mechanical vibrations under the excitation of a piezoelectric crystal, and the vibration has a certain frequency and amplitude. When the tuning fork is submerged by liquid or solid, the vibration frequency and amplitude of the tuning fork will change. This frequency change is detected by the electronic circuit and outputs a switching signal.
