Factory PTFE Tuning Fork Liquid Level Switch / Level Sensor

Part Number: YH300F-100ASN

Part Name :  Tuning Fork Level Switch

The tuning fork type level switch is a general-purpose level limit switch. The tuning fork is excited by a piezoelectric crystal to generate vibration The vibration frequency changes when the tuning fork is submerged by liquid or solid. This frequency change is detected by the electronic circuit and outputs a switching amount. The tuning fork type position limit switch is not affected by the dielectric parameters of the medium and the factors of turbulence, agitation, air bubbles, vibration, etc. There are no moving parts, so no maintenance and adjustment are required. It is an ideal choice for level switches in complex working conditions.

Working principle: Drive the tuning fork rod through the piezoelectric wafer and accept it from another piezoelectric wafer Vibrating signal, so that the vibration signal can be circulated, and the sensor rod is generated Vibration. When the material comes into contact with thesensor bar, the vibration signal gradually becomes smaller until When the resonance stops, the control circuit outputs an electrical contact signal.
