Low And High Alarm Rob Type Solid Rf Admittance Level Switch
Rf Admittance Level Switch Working Principle
Because the energized probe and the container wall constitute the two polar plates of the capacitor, the insulator of the probe and the surrounding air become the dielectric material, when the air (whose dielectric constant is 1.0) is replaced by any other material (the dielectric constant > 1), The capacitive effect is enhanced, thus changing the impedance of the application. That is, the change of capacitance value causes the change of impedance. This effect is measured by the circuit and compared to the reference established by the sensitivity setting (circuit).
Rf Admittance Level Switch Design Feature
◎High and low temperature resistance: Suitable for working environment from -184°C to 280°C, and ceramic probes suitable for higher temperatures are also available;
◎Output form: Double-pole double-throw relay signal output, at the same time there is a status light to display the output status, and a delay function of 0 to 30 seconds.
◎Intelligent diagnosis: After the power is turned on, the instrument circuit automatically detects whether the working state is normal.
