Rf Admittance Type Level Switch is based on radio frequency (RF) capacitor technology. Apply a radio frequency to the probe, and through continuous analysis, determine the impact caused by the surrounding environment. The energized probe and the container wall constitute the two plates of the capacitor. The insulator of the probe and the surrounding air become dielectric materials. When air is replaced by any other material, changed the impedance of the application, the change in capacitance caused the change in impedance. After this influence is measured by the circuit, it is compared with the reference established by the sensitivity setting (circuit).
