Contacting Electrode
Method (used with
Rigid Metal Electrode )
This method uses Rigid electrodes which make contact directly the
surface of the test material. This method is applicable for thick,
smooth or slightly compressible materials . The merits and demerits of
this method are as follows:
Merits
Procedure to measure capacitance is simple
It is not necessary to apply thin lm electrodes
Equations to obtain dielectric constant are simple
Demerits
Air lm (error caused by air gap between electrodes and surface
of the test material) causes error .
Principle
Figure 3-7 shows the schematic electrode structure for this method.
