NYSP-UK865 RF Admittance Level Switch Working Principle
Radio Frequency Conductivity level switches work on the principle of backbone Radio Frequency (RF) capacitance technology. RF is applied to the probe and the impact caused by the surrounding environment is determined by continuous analysis. Since all materials have a dielectric constant and their conductivity differs from that of air, the overall impedance, reflected by the small capacitance shift, changes when the probe comes in contact with the material. Since the energized probe and the vessel wall form the two pole plates of a capacitor, when air (with a dielectric constant of 10) is replaced by any other material (with a dielectric constant > 1), the capacitive effect is enhanced. This changes the negative resistance of the application. That is, the change in capacitance value causes a change in impedance. This effect is measured by the circuit and compared with the reference value established by the sensitivity setting (circuit).

NYSP-UK865 RF Admittance Level Switch Design Feature
1.Versatile: Can be used with a variety of conductive and non-conductive media such as liquids, sticky materials, particles, powders and fly ash.
2.Anti-stick: Patented anti-stick circuitry eliminates false signals caused by material adhesion.
3.Removable Probe: No cable connection between the controller and probe, so the controller can be removed and replaced at any time without affecting incoming or outgoing material.
4.High and low temperature resistance: suitable for operating environments from -184°C to 280°C, ceramic probes for higher temperatures are also available.
5.Output form: double-knife double-throw relay signal output, while there is a status light to show the output status and a 0 to 30 seconds delay function.
6.Non-intelligent diagnosis: the instrument circuit automatically detects whether the working status is normal after power on.
