LB Miniature Radio Frequency Admittance Material Level Switches

LB miniature radio frequency admittance material level switching using phase-shifting technique to detect there is no material in the silo level controller. Detection circuit using the dielectric constant and conductivity of material and air differences were detected, detect changed signal after the electrodes touch the items, alarm signal upon detection circuit. For using technique of radio frequency admittance (reciprocal of reactance) for testing, it is called radio frequency admittance material level switches. Due to existence of protection of electrodes detection circuit and protection of electrodes detection electrode compared to the signal, which overcome the influence of adhesion of materials for level measurement.
