Let us consider the principle underlying the measurement of pulp density by the capacitive method in the case of a non-contact two-electrode measuring cell. In the analysis we will use the equation for the imaginary Bp component of the conductivity of the equivalent circuit of the cell ...
The objective of the study was to investigate the potential electric fields of a seven-electrode conductometric transducer in order to find its optimal design parameters. Since the seven-electrode converter is two four-electrode cells connected in series, modeling was performed for the case of a four-electrode primary converter .....
The density of liquid products in mineral processing is the most important parameter by means of which it is possible to influence and control the course of technological processes. ...
Piezoelectric sensors of the volumetric type are widely used in the measurement of rapidly changing pressures. This is explained by their lack of inertia, the possibility of obtaining with their help quantitative and qualitative characteristics of the studied value and linearity of the piezoelectric effect...
In the high-frequency moisture-metric system, developed at the Leningrad Mining Institute and designed for express determination of moisture content of apatite concentrate, the output parameter is the capacity...
The problem of studying physical phenomena during an explosion is currently very relevant. Some explosion processes have such short durations that only electronic equipment can detect them. The presence of a pronounced piezoelectric effect in some crystals, as well as in all ferroelectrics, makes it possible to develop low-inertia methods for measuring pressures, including shock wave pressure. Piezoelectric sensors have been used to study shock waves both here and abroad...
The electrophysical properties of materials are influenced by many factors: humidity, temperature, granulometric and chemical compositions, etc. Therefore, the total differential, for example, of the volumetric resistance of saltpeter can be represented as ...
