NYSP RF Admittance Switch
NYSP RF Admittance Switch Operating Principle
The principle of RF admittance level switch is based on RF (RF) capacitor technology. A radio frequency is applied to the probe to determine the impact caused by the surrounding environment through continuous analysis. Because all the materials have dielectric constant and their conductivity is different from that of air, the total impedance reflected by the small capacitance deviation of the probe changes when the probe is in contact with the material. Because the electric probe and the wall of the container form the two polar plates of the capacitor, the insulator of the probe and the surrounding air become dielectric materials, when the air (whose dielectric constant is 1.0) is replaced by any other material (dielectric constant > 1), Capacitance effect To strengthen. Thus, the impedance of the application field is changed. The change of capacitance caused the change of impedance. This effect is measured by the circuit and compared with the reference set up by the sensitivity setting (circuit)
The correct setting ofRF 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 material accumulated on the probe, otherwise it will cause the fault of sensitivity. The Null-KoTeTM circuit uses the same wireless frequency and potential excitation as the sensor probe. Because the current does not flow at the same potential, the Null-KoTeTM circuit separates the current from the current normally flowing from the electric probe through the stack of materials to the wall of the vessel. So you measure the material around the probe, not the material that's piled up.
