Abstract

A method is offered and the device bringing into effect this method which excludes the impact of electrode wear and inter-electrode space on metrological parameters of moisture indicators is presented. It is shown that by use of the known capacitance sensors with the help of the proposed algorithm of transformation it is possible to switch from the capacitance meters of dispersion material composition to pure dielcometric meters. In this situation metrological parameters do not depend on part specifications of their sensors. In addition the impact of all non-diagnostic markers is excluded in this device.
