SCL Sanitary Tuning Fork Level Switch

It is durable and easy to use, non calibration required. Wide voltage supply range 20-250Vac/dc 50/60Hz Hihg / low faillure safe modes . SPDT Relay output / SSR MOSFET output. It is suitable for detecting the level inbins , silos, and hoppers, which filled with powdered materials Of diferente density .

The tuning fork of level switch operated by using two piezoelectric elements built-in on vibration tube. The first piezoelectric element triggered by pulse signal that created from circuit to transport vibration energy out, and the other piezoelectric element receives the vibration and transmits it to output electric signal. While the probe contacts material, it will cause the frequency change of output signal and the vibration will hold and send out the relay on at the same time. Tuning fork of level switch provides reliable & maintenance-free for bulk solids. Just a simple mounting and calibration procedure that keep your facility in save and monitoring. This device can withstand fiercely  lateral loads and static electricity. 
For friendly use, Fail-safe is equipped as standard to prevent malfunction caused by power shortage.
