SC1400

The SC series consists of vibration level sensors with tuning fork elements that use piezoelectric crystals and semiconductor electronics technology to generate vibrations in the tuning fork element at a specific frequency and receive electronic feedback. When the probe element makes contact with the target material, the vibrations are dampened, and the electronic feedback changes, with the presence of the material being detected by the electronics, which changes the sensor output state, indicating the presence of the material. When the probe element no longer makes contact with the target material, vibrations are generated again, and the output state returns to indicating the absence of the material.

Main features:

• Double insulation reduces PCB damage caused by large temperature changes.
• Suitable for liquid, bulk, and solid applications.
• Sensitivity adjustment available for different material densities. Capable of detecting fine powder.
• No frequent calibration required, easy to use, robust and durable construction.
• SPDT relay output, SSR MOSFET output.
• Wide power supply voltage range 20~250 V AC/DC, 50/60Hz.
