Rod Type Ceramics High Temperature NYSP-L863 RF Admittance Level Switch For Material And Liquid
NYSP-L863 RF Admittance Level Switch Working Principle
The radio frequency admittance level switch working principle is based on radio frequency (RF) capacitive technology. A radio frequency is applied to the probe and through continuous analysis, the effects caused by the surrounding environment are determined. Since all materials have a permittivity and their conductivity is different from that of air, the overall impedance reflected by the small capacitance shift changes when the probe is in contact with the material. Because the energized probe and the vessel wall form 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. The change of capacitance value causes the change of impedance. This effect is measured by the circuit and compared to a reference established by the sensitivity setting (circuit).

NYSP-L863 RF Admittance Level Switch Design Features
1.Strong versatility: It can be applied to the measurement of various conductive and non-conductive media, such as liquids, viscous substances, particles, powders, and fly ash.
2.Anti-adhesion: The patented anti-adhesion circuit can eliminate false signals caused by material adhesion.
3.Detachable probe: There is no cable connection between the controller and the probe. The controller can be removed and replaced at any time for maintenance without affecting the incoming and outgoing materials.
4.High and low temperature resistance: suitable for working environment from -184°C to 280°C, and ceramic probes for higher temperature are also available.
5.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.
6.Intelligent diagnosis: After the power is turned on, the instrument circuit automatically detects whether the working state is normal.
