The working principle is based on radio frequency (RF) capacitor technology. A radio frequency is applied to the probe, and through continuous analysis, the influence caused by the surrounding environment is determined. Because all materials have a dielectric constant and their conductivity is different from air, the total impedance reflected by the slight capacitance shift when the probe is in contact with the material changes. Because the energized probe and the container wall constitute the two plates of the capacitor, the insulator of the probe and the surrounding air become dielectric materials. When the air (its dielectric constant is 1.0) is replaced by any other material (the dielectric constant> 1) When the capacitance value changes, the impedance changes. After this effect is measured by the circuit, it is compared with a reference established by the sensitivity device setting (circuit). The radio frequency admittance oil-water interface instrument can detect any process materials, such as refined oil, gasoline, conductive mud, etc.
