The working principle of RF admittance level switch

　　Radio frequency admittance switches, also known as radio frequency admittance level switches, radio frequency admittance level switches, radio frequency admittance level meters, or radio frequency admittance level meters, have a wide range of applications in power plants, oil fields, chemical engineering, papermaking, metallurgy, and other fields. Let's briefly understand the working principle of RF admittance level switches.

　　The radio frequency admittance switch measures and controls the level of materials by sensing the changes in reactance (capacitance and impedance) between it and the tank body through a probe. The internal electronic unit consists of a probe measuring the reactance between the electrode and the unloaded tank, forming a balanced bridge circuit and generating a stable oscillation signal.

　　The RF admittance level switch has the characteristics of easy installation, accurate measurement, prevention of material hanging, and strong practicality. Its working principle is to measure and control the material level by sensing the changes in reactance (capacitance and impedance) between it and the tank body through a probe.
