Products Description
Radio Frequency Admittance Level Switch Working Principle
The working principle of RF admittance level switch is based on RF capacitance technology. Apply a radio frequency to the probe, and determine the impact caused by the surrounding environment through continuous analysis. Because all materials have dielectric constants and their conductivity is different from that of air, the total impedance reflected by the small capacitance shift changes when the probe contacts the material. Because the energized probe and the container wall constitute two plates of the capacitor, the insulator of the probe and the surrounding air become dielectric materials. When air (whose dielectric constant is 1.0) is replaced by any other material (dielectric constant > 1), the capacitance effect is strengthened. Thereby changing the impedance of the application. That is, the change of the capacitance value causes the change of the impedance. This effect is measured by the circuit and then compared with the reference established by the sensitivity setting (circuit).
The correct setting of RF admittance level switch sensitivity will affect the correct change of sensor output. The Null-KoTeTM circuit of the probe can make the measuring circuit ignore the materials accumulated on the probe, otherwise it will cause sensitivity failure. The Null-KoTeTM circuit is excited with the same radio frequency potential applied to the sensing probe.
Since the current cannot flow at the same potential, the Null-KoTeTM circuit blocks the current flow from the energized probe through the stacked materials to the container wall. In this way, the materials around the energized probe are measured, not the accumulated materials.
