Liquid Level Switch

Piezoelectric devices are utilized to achieve vibration drive and detection. Once resonant vibrating fork comes in contact with measured medium, vibration frequency of forks substantially decreases, and the output signal from piezoelectric detection device decreases accordingly. Then an integrated circuit is designed to analyze the signal from piezoelectric device and output a switch signal as a result.

Features

(1) High reliability due to the detection of vibration frequency.

(2) With strong disturbance resistance ability, not influenced by foam, bubbles, viscosity, vibration and other liquid characteristics.

(3) Easy installation and maintenance free.

(4) With self-checking and real-time status monitoring functions.
