Xiangtan Steel Plant RF Debugging

Installation and commissioning of RF admittance at Xiangtan Steel Plant

Ultra high temperature RF admittance level gauge/high temperature bin pump level gauge, with a temperature resistance of up to 1300 degreesThe working principle is based on radio frequency (RF) capacitor technology. Apply a radio frequency to the probe and determine the impact caused by the surrounding environment through continuous analysis. Due to all materials
All materials have a dielectric constant, and their conductivity is different from that of air. When the probe comes into contact with the material, the total impedance reflected by the small capacitance offset changes. Because the energized probe and container wall form the two plates of the capacitor, the insulator of the probe and the surrounding air become dielectric materials. When air (with a dielectric constant of 1. o) is replaced by any other material with a valence constant greater than 1, the capacitance effect is enhanced. Thus changing the impedance of the application scenario. The change in capacitance value causes a change in impedance. After this influence is measured by the circuit, it is compared with the reference benchmark established by the sensitivity setting (circuit). The correct sensitivity setting will affect the correct variation of sensor output. The anti adhesion circuit of the probe can enable the measurement circuit to ignore the radio frequency potential excitation of the accumulated material on the probe. Due to the inability of current to flow at the same potential, the anti adhesion circuit blocks the flow of current from the energized probe through the accumulated material to the container wall. This measures the material around the energized probe, rather than the adhered and accumulated material.
