Rod - type RF Admittance Switch for High and Low Level Alarms in Liquid, Dust, Particle, Solid and Other Media Probe material:304 4-20mA loop-powered (no external power)The radio frequency admittance level switch works based on RF capacitive technology. A radio frequency is applied to the probe, and the circuit measures impedance changes caused by material air dielectric constant differences, comparing them with a sensitivity set reference. It has multiple advantages: strong versatility for various conductive and non conductive media; a patented anti adhesion circuit to eliminate false signals from material adhesion;
