Principle 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.
FeaturesSturdy and durable design. No calibration needed. Special design to avoid the accumulation of material on probe. High / Low fail safe modes Field-operatable in sensitivity adjustment to fit versatile density of material.
