The RF admittance switch adopts advanced RF admittance technology, overcoming the defect that capacitive level switches cannot eliminate the influence of conductive hanging materials. The instrument operates reliably, and all technical indicators meet the international level of similar products. It is widely used for alarm and control of liquids, slurries, dust, material levels, and two types of liquid interface liquid levels. In addition, the product has added on-site working status indication, making it a very stable and reliable liquid level switch with a very high cost performance ratio< Br/>








The RF admittance switch is composed of a sensor electronic unit, which mainly includes three parts: a measuring probe, a shielding electrode, and a grounding terminal. The height of the material is reflected by the change in admittance between the probe and the container wall. When the material reaches the switch operation point, the electronic unit responds, drives the relay, and outputs a switch signal. Shielding electrodes can prevent errors caused by hanging materials on the electrodes. The action signal only outputs the switch control signal when the material actually reaches the set point< Br/>
