Product Description

DPDTSPDT signal vibrating tuning fork liquid water level switch with high low level alarm 

                               Vibrating Tuning Fork Level Switch

 

 

Product description:

Tuning fork level switch is a kind of new control switch, which is mainly depend on the tuning fork through 

the vibration principle to measure the level of material. Through the installation of the tuning fork on the

base of the tuning fork vibration of a piezoelectric crystal in the resonance frequency. When the tuning 

fork and the medium contact, tuning fork frequency and amplitude changes, these changes are detected by 

the intelligent circuit, and converts it into a switch signal.
