Microwave level switch

The tuning fork level switch has piezoelectric components, which are used for driving and signal feedback to cause resonance of the probe. When a material level comes into contact with the probe, the tuning fork level switch will stop vibration and output a grounding signal. The tuning fork level switch relies on the damping effect generated when the measured object is wrapped around the probe to stop resonance and output a switch signal. Therefore, there is no signal amplification circuit inside the tuning fork level switch, which can avoid the trouble of frequently adjusting sensitivity due to changes in material properties.
