The RF admittance level switch is composed of a sensor unit and an electronic unit. The sensor unit mainly includes three parts: measuring probe, shielding pole and grounding terminal. The height of the material is reflected as the change of admittance between the probe and the container wall. When the material reaches the switch operating point, the electronic unit reacts to drive the relay action and output the switch signal. Shielding pole can be prevented due to electrode. There is a hanging material on the wrong action signal, only when the material really reaches the setting point, the switch control signal is output.
Dielectric conductivity and temperature have little effect on capacitance. High anti-interference and stability
Capable of measuring highly corrosive liquid and solid particles
