RF ADMITTANCE SWITCH HNL50-A

The HNL50-A RF admittance level switch consists of a sensor unit and an electronic unit. The sensor unit mainly includes three parts: measuring probe, shieldingelectrode, and grounding terminal. The height of the material is reflected by thechange in admittance between the probe and the container wall. When the material reaches the switch working point, the electronic unit reacts, drives the relayto act, and outputs the switch sianal. Shielding electrodes can prevent misopera-tion signals caused by hanging materials on the electrodes, and only outputswitch control signals when the materials truly reach the set point.
