Knowledge about RF Admittance Level Switch

How does RF Admittance Level Sensor Work?

The RF admittance level switch working principle is rooted in radio frequency (RF) capacitor technology. This device employs the application of radio frequency to a probing element, allowing for a continuous analysis of the interactions within its surrounding environment. The probe, when energized, acts in conjunction with the container wall, effectively forming the two plates of a capacitor. In this configuration, the probe’s insulating material and the surrounding air serve as dielectric components. It’s important to note that all materials possess a dielectric constant greater than that of air.

When any substance other than air occupies the space, the capacitance effect is heightened, resulting in a modification of the device’s impedance. This change in capacitance subsequently triggers a discernible alteration in impedance, which is detected by the circuitry. This detected change is then compared against a predetermined reference value, set by the sensitivity adjustment of the circuit.

Radio frequency admittance, as referenced here, represents the reciprocal of electrical impedance. Comprising resistive, capacitive, and inductive components, radio frequency refers to the higher frequency range within the radio spectrum. Consequently, radio frequency admittance involves utilizing high-frequency radio waves to gauge admittance. In the operational context, the level switch’s sensor establishes an admittance value with both the container wall and the substance being measured. As the material level experiences variations, the admittance value undergoes corresponding changes. These alterations are then translated by the circuitry unit into a level signal output, thus facilitating an effective and accurate level measurement process.
