One of the quality indicators of the produced mining and chemical raw materials and processed products is their moisture content. Reliable control of humidity requires a lot of labor and time.

The process control system of Nalchik hydromet plant requires operative information on humidity of initial industrial products of KSMP. The currently used thermogravimetric method requires 4 hours for drying of industrial products at a temperature of 105°C to a constant weight ...

When controlling the moisture content of materials with large dielectric losses, schemes that allow measuring the components of the complex resistance of the capacitive transducer are usually used. The greatest sensitivity among them is characterized by bridge meters ...

In resonant methods of moisture control, a capacitive sensor with the analysed material is in some cases included in the oscillating circuit of an autogenerator. ...

Selection and maintenance of optimal technological modes of preparation and briquetting, conditions of coal storage and transportation require prompt and objective autocontrol of its humidity. ...

Moisture content is one of the quality indicators of coal and coal products. Measurement of moisture content of materials of low goodness is a difficult task and not finally solved.

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.

Creation of the system for express discrete determinations of phosphate flour moisture content within 0-3,5% was preceded by the study of its electrophysical properties. For this purpose, the dependence lg r = F₁ (W) (g and W - respectively the volume resistivity and moisture content of phosphate flour) was obtained at direct current.
