SC35 Tuning Fork Level Sensor

The SC series are vibratory level sensors with tuning fork prongs, utilizing piezoelectric crystals and semiconductor electronics technology to generate vibrations in the prong element at a specific frequency and receive electronic feedback. When the probe element comes into contact with the target material, the vibrations are dampened, the electronic feedback changes, and the presence of the material is detected by the electronics, which changes the sensor output state, indicating the presence of material. When the probe element is no longer in contact with the target material, the vibrations are regenerated, and the output state returns to indicate the absence of material.

Main features:

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

Applications:

The device is used to detect the maximum and minimum levels of tanks or pipes filled with various solid/liquid materials. Example substances whose levels can be measured include:

  • Granular materials:
    • Powdered milk
    • Sugar
    • Tea
    • Salt
    • Gravel
  • Liquids:
    • Water
    • General-purpose solvent
    • Heavy oil
    • Petroleum
    • Ink

Industries where the sensors can be used:

  • Chemical fibers industry
  • Cement industry
  • Steel industry
  • Food industry
  • Pharmaceutical industry
