1. Introduction

The tuning fork level switch is a mechanical resonant device which excited by
piezoelectric (PZT) elements. When the measured medium comes into contact
with the tuning fork, it will change the feedback resonant frequency due to the
damping resonances between the exciting PZT and receiving PZT. By
detecting the frequency and appropriately tuning the sensitivity of tuning fork
level switch on measured material, such device can easily operate for
monitoring the alarm level of measured material.

2. Feature

1. Providing a universal power supply for operating in voltage range of
20 to 250 (Vac / Vdc).

2. No calibration or complex setting procedure are needed, robust, free of
maintenance.

3. High / Low fail safe modes provide user the safety monitoring and real time
communication.

4. Equipped with Remote Self-Testing function (RST) to diagnostic the hardware
connection with peripherals
