Radio Frequency Capacitance Liquid Level Meter 24VDC Safe Precision
Radio Frequency Capacitance Liquid Level Meter Discription
The working principle of the radio frequency capacitance level meter is based on radio frequency (RF) capacitance technology. A radio frequency is applied to the probe, and through continuous analysis, the influence of the surrounding environment is determined. Since all materials have a dielectric constant and their conductivity is different from that of air, when the probe is in contact with the material, the total impedance reflected by the small capacitance shift changes.
