Extension of the limits and improvement of the measurement accuracy of high-frequency moisture meters on the basis of an E12-1A type capacitance meter
Abstract
In discrete rapid monitoring of the moisture content of dispersed materials, devices based on the E12-1A instrument, whose simplified circuit is shown in Figure 1, are in some cases used. The range and accuracy of moisture measurements of materials are determined not only by the design of the sensor, but also by the circuit of the measuring oscillator. The range of moisture measurement can also be extended and the effect of losses reduced by increasing the overall gain of the stage, for example, by replacing the cathode follower with an aperiodic amplifier with an anode load.
