Corrosive Liquid Radio Frequency Capacitance Level Gauge Strong Anti-Interference Ability

Working Principle of Radio Frequency Capacitance Level Gauge

The working principle of RF capacitance level gauge is based on RF capacitance technology. Apply a radio frequency to the probe and determine the impact of the surrounding environment through continuous analysis. Because all materials have dielectric constant and their conductivity is different from that of air, when the probe contacts with the material, the total impedance reflected by the small capacitance shift changes. Because the energized probe and the container wall constitute two plates of the capacitor, the insulator of the probe and the surrounding air become dielectric materials. When air (dielectric constant is 1.0) is replaced by any other material (dielectric constant > 1.0), the change of capacitance value causes the change of impedance. This effect is measured by the circuit and then compared with the reference established by the sensitivity setting (circuit).

Design Features of Radio Frequency Capacitance Level Gauge
