The measurement principle of the RF admittance level switch is based on the principle of capacitance. The probe and the container wall in the container form two plates of a capacitor. When the medium between the two plates of the capacitor changes, the capacitance value also occurs. Variety. The measurement principle can be expressed by the following formula: In order to study the relationship between material permittivity and capacitance change, 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=10mm, ε=51, find the relationship between △C and H From the above, it can be seen that the larger the dielectric constant, the larger the capacitance change value and the higher the sensitivity.
