Varicaps to increase sensitivity of capacitive moisture meters
Abstract
Numerous methods of measuring the moisture content of solid, liquid and bulk materials are known: conductometric, based on the use of the relationship between moisture and the active resistance of the material; capacitive - between moisture and dielectric constant (more precisely - apparent capacitance); neutron; nuclear magnetic resonance - yamr, etc.
