NYDR-3051 RF Capacitor Level Meter Working Principle
The RF capacitance level meter works on the basis of radio frequency (RF) capacitance technology. A radio frequency is applied to the probe and the effect caused by the surrounding environment is determined by continuous analysis. Since all materials have a dielectric constant and their conductivity is different from that of air, the total impedance reacted to by small capacitance shifts changes when the probe is in contact with the material. Because the energized probe and the vessel wall form the two pole plates of the capacitor, the insulator of the probe and the surrounding air become the dielectric material, and when air (dielectric constant of 1.0) is replaced by any other material (dielectric constant >10), the change in capacitance value causes a change in impedance. This effect is measured by the circuit and then compared with the reference reference frame established by the sensitivity setting (circuit).
