Product introduction
Introduction
The radio frequency admittance switch is composed of a measuring pole, a shielding pole, and a grounding pole (the threaded part of the installation). When the measuring pole is covered by the material, the admittance value becomes larger, and a switching signal or an alarm current signal is output.The shielding pole is located between the measuring pole and the grounding pole. The signal waveform is exactly the same as the measuring pole, and the two are completely isolated. When the material is attached to the terminal electrode itself, the admittance change between the measuring pole and the grounding pole can be suppressed, and the admittance change between the measuring pole and the tank wall can only be sensed, which can eliminate the error signal generated by the material attachment.
