Intelligent Diagnosis RF Admittance Switch High And Low Temperature Resistance
Working Principle of RF Admittance Switch
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).
Design feature of RF Admittance Switch
◎ High and low temperature resistance: suitable for the working environment of - 184 ℃ to 280 ℃, and ceramic probes suitable for higher temperatures can be provided.
◎ output form: double pole double throw relay signal output, and a status lamp displays the output status, with a delay function of 0 to 30 seconds
◎ intelligent diagnosis: after turn on, the instrument circuit automatically detects whether the working state is normal.
◎ Strong versatility: it can be applied to the measurement of various conductive and non-conductive media, such as liquid, viscous substance, particle, powder and fly ash
◎anti adhesion: the patented anti adhesion circuit can eliminate false signals caused by material adhesion.
◎ detachable probe: there is no cable connection between the controller and the probe, and the controller can be removed, replaced and repaired at any time, without affecting the incoming and outgoing materials.
