Tuning Fork Level Switch

UVVF Tuning Fork Level Switch probe is based on a tuning fork harmonic resonance. It utilizes piezoelectric devices to drive the fork to vibrate and detect the changes of vibration. The fork vibrates in resonant frequency when it does not contact with medium. Once the fork comes in contact with medium, vibrating amplitude of the fork will decrease substantially. Output from the detecting piezoelectric device will decrease accordingly. An integrated circuit is designed to analyze the amount of decrease and output a switch signal.

Features

(1) Reasonable design of tines and precisely adjusted of fork resonant frequency. The lowest measurable density can be as low as 0.008g/cm³.

(2) Industry-leading performance for high temperature working environment, can tolerate process temperature up to 250℃.

(3) Made of strong corrosion resistant material 304 or 316L.

(4) Easy installation and maintenance free.
