High Reliability FineTek SC Tuning Fork Sensor Vibrating Probe Level Switch

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. 

• Glass window, to review power supply and output directly without having to take off enclosure cover (SC 3 series).
• Dual insulation can reduce damage on PCB board caused by temperature, humidity, and condensation effects.
• Wide voltage supply range 20~250, 50~60Hz Vac/Vdc.
• SPDT Relay output, SSR MOSFET output.
• No calibration required, easy use, sturdy and durable design.
• High / Low failure safe modes.
• Sensitivity adjustment is abailable for different density of media. Fine power can be detected.
• Suitable for liquid, power, solid applications.

• Most materials in powder can be measurable, includes the grounded coffee, milk power, chocolate, coal ash, bulk, sugar, salt, wheat, grains, glass debris, plastic pellet, cement.
• Sludge level detection in waste water.

The SC series detects the min. and max of level in bins, silos and hoppers, filled with powdered materials. The following list shows its applications.
