Working Principal of Piezoelectric actuator for tuning fork switch:

The tuning fork switch uses piezoelectric ceramic parts to realize the vibration drive and detection of the fork body. After a pair of piezoelectric ceramic crystals mounted on the base of the tuning fork, the excitation type is applied to the fork body, and the fork body resonates at a certain frequency. When the tuning fork is immersed in liquid or solid, the vibration frequency of the tuning fork changes, the vibration frequency changes directly on the output signal of the piezoelectric ceramic device, and the detection circuit intelligently analyzes the frequency change and outputs a switching signal, thereby achieving The purpose of alarm or control; widely used in food, beverage, pharmaceutical, feed, fertilizer, petroleum, metallurgy, chemical, cement, environmental protection and other industries to achieve the upper and lower limits of liquid or material level alarm and control.

 

Applications:

1. Tuning fork level switch

2. Tuning fork liquid level switch

3. Tuning fork material level switch

4. Tuning fork vibrating switch
