NYSP-UK866 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-UK866 RF Admittance Level Switch Design Feature
1.Strong versatility: it can measure liquid level and material level, also can meet the requirements of different temperature, pressure, mediums. Also can be used in corrosion, impact and other bad occasions.
2.Anti-hanging of material: the unique circuit design and sensor structure make its measurement free from the influence of the sensor hanging material, no need to clean regularly, and avoid mismeasurement.
3.Maintenance-free: no moving parts during measuring, no mechnical parts damage problem , no need regular maintenance.
4.Anti-interference: contact measurement, strong anti-interference ability, can overcome the influence of steam, foam and agitation.
5.Accurate and reliable: the measurement quantity is diversified, which makes the measurement more accurate. Not affected by environmental changes, with high stability and long service life.
