80g cable type RF admittance level switch

  Principle:   There is capacitance between the detection rod of RF admittance and the metal container wall, which forms a bridge circuit, and the RF oscillation signal generated by the oscillation circuit is added to the bridge
When the measured medium does not contact the probe rod, the bridge is in a balanced state and no output signal
When the measured medium is filled between the probe rod and the tank wall, because the electrical characteristics of the measured medium are different from that of air, it will cause the imbalance of the bridge circuit and produce the output signal
