The measurement of the RF admittance level switch is based on the principle of capacitance. The probe in the container and the wall of the container form two plates of a capacitor. When the medium between the two plates of the capacitor changes, the capacitance value also changes. . The measurement principle formula is expressed as: In order to study the relationship between probe diameter and capacitance changes, we make the following assumptions: The first case: D=2000mm, d=10mm, ε=2, find the relationship between △C and H The second case: D=2000mm, d=8mm, ε=2, find the relationship between △C and H From the above, it can be seen that the larger the diameter of the RF admittance level switch probe is, the higher the sensitivity is; in addition, the closer D and d are, that is, the smaller the distance between the two electrodes is, the higher the sensitivity of the meter is.
