At the same time, the tangent value of loss angle not only depends on the loss caused by the direct current passing through the conductivity(white corundum), but also depends on other losses related to the complete, bipolar, structural and other types of energy polarization. However, it should be pointed out that the tangent value of loss angle depends on the moisture content to a great extent(aluminum oxide sandblasting).

Generally, the capacitance sensor belonging to air capacitor is used in measurement(brown fused aluminum oxide). The equivalent circuit of the sensor is parallel capacitance C and effective resistance R, whose value depends not only on the coefficient to be measured of the material, but also on the structural characteristics of the sensor, that is, the distance between the plates of the capacitor(carborundum grit suppliers), the edge effect, the parasitic capacitance and the leakage resistance.

In the inspection of granular materials or molding materials, in which the materials to be inspected are installed(black aluminum oxide). As in the case of the conductance hygrometer, the indication of the instrument used to measure the moisture content of the crushed abrasive and the molding material depends to a large extent on the particle size and shape(silicon carbide grit suppliers), that is, the type of material, the degree of compaction of the material in the sensor, etc.

The sensor structure is determined by the type of materials to be tested: granular materials, molding materials, parts, etc(pink aluminum oxide). The sensor used for the inspection of consolidated products can be placed in them or pasted sensors can be used, i.e. the sensor is in contact with the surface of the products(fused alumina); when inspecting abrasive products, the latter type of sensor is good because it is easy to contact with the products to be inspected.

The measurement of humidity by dielectric method is to measure the dielectric coefficient, loss tangent and full (complex) dielectric coefficient of materials(white fused alumina). When measuring the humidity of materials, the cylinder capacitor sensor is usually used, whether the frequency range is reasonable or not is also related to the polarization characteristics of the dielectric and the physical properties (such as viscosity) of the water medium(carborundum powder).

When this type of sensor is used to measure(silicon carbide price), only the conductivity and capacitance of the layer of material close to the surface of the sample to be tested are measured, so the indication of the instrument is a function of the sample geometry (thickness). The capacitive hygrometer also has its own shortcomings(aluminum oxide blasting). The resonance circuit is connected to the bridge differential measurement circuit and the oscillation generator circuit.

At present, like the conductance type, it is difficult to eliminate its shortcomings, so its use is limited. Their working surfaces are in the same plane(white aluminum oxide). The loss tangent is related to the mechanical and chemical composition and temperature of the material to be tested, there is an oscillating circuit, such as oilstone and grinding wheel, the insulation of the medium(silicon carbide abrasive powder), so it is possible to test the humidity by measuring TG value.

Adhesive sensors are usually made into two or more metal rings which are insulated from each other(arc fused alumina). The ab3-2 hygrometer used to measure abrasive products and the hygrometer designed by samoylianko engineer are the sensors of this type. The measuring circuit of the capacitance hygrometer is generally designed according to the type of resonant capacitance meter(alumina polishing powder), and its capacitance is the capacitance of the sensor.
