Radio frequency admittance level switch

Radio frequency admittance level switches are widely used in petrochemical, metallurgical, electric power, medicine, food, paper, building materials and other industrial fields. This product uses high-frequency technology to generate a low-power radio frequency signal on the probe from the electronic circuit. The probe acts as a sensitive element and feeds back the signal changes caused by the dielectric constant of the material level to the electronic circuit. These changes include capacity and conductance. Change, so the electronic circuit processes the comprehensive change signal of capacitive reactance and impedance, and then changes the output state of the relay. It is an improved radio frequency admittance measurement technology based on the original capacitance measurement, and represents a new level of current level measurement.
