Principle of measurement

As shown in the figure below, the principle of parallel plate capacitor is applied to the PS sensor. Suppose the electrostatic capacitance between the center electrode and the target is “C”, the inductivity and distance between probe and the target are “ε” and “g,” and center electrode surface area is “A”, then, electrostatic capacitance can be calculated by the following formula:

In addition, by using AC constant current power supply as shown in the figure, the output voltage, calculated by the following formula, will be relative to the gap between sensor and the target object:

To achieve high linearity, parallel electric field is obtained at the center of electrode by equalizing the electric potential level of guard electrode and the center electrode.

 

Specifications
