The belt-type online microwave moisture detector for wood blocks, bamboo chips, coal, and sintering materials is mainly used for online detection of moisture in raw materials such as wood blocks, bamboo chips, coal, sintering materials, and coke.

It is used for quality and cost management and control in the production process, and cost settlement in the process of raw material acquisition. The measurement method is non-contact measurement, which can automatically, quickly, accurately, stably, and continuously measure the moisture content of raw materials in real time. It can be seamlessly connected with management control systems such as DCS/ERP.

This microwave is a 2.4GHz microwave (can penetrate high-density and wide belts). The attenuation and phase change generated when the microwave penetrates the medium are mainly determined by the dielectric constant and dielectric loss tangent of the medium. Water is a polar molecule, and the dielectric constant and dielectric loss tangent of water are much higher than those of general media.

Usually, the dielectric constant of a water-containing medium is mainly determined by its moisture content. The microwave transmits energy from the microwave transmitting probe located above the conveyor belt, and after passing through the belt and the material, the remaining microwave energy is received by the microwave receiving probe at the lower end of the belt.

According to the change in the attenuation of the microwave power and the instantaneous total mass calculated by the ultrasonic mass compensation probe, the moisture content of the material can be calculated based on the percentage content of the total energy lost and the total mass using the microcomputer system software.

Since the microwave completely penetrates the process material, all physical moisture can be measured. This is not only applicable to surface moisture, but also to internal moisture.

This technology ensures high measurement accuracy and precision. The color and surface structure of the material, water vapor and dust will not affect the measurement results.

And, it is also suitable for the pharmaceutical industry, wood industry, chemical industry, glass fiber industry, etc.

10. Measurement method: microwave penetration.

11. Configuration: energy transmitting probe, receiving probe, height compensation probe, dedicated industrial computer software.

The installation method is: the transmitting probe is installed at the lower end of the conveyor belt, and the receiving probe and ultrasonic mass wavelength probe are installed directly above the conveyor belt.

The moisture meter can be installed in different application environments, such as pipes (no metal), containers, funnels and conveyor belts. In general, the microwave moisture meter needs to be equipped with a non-contact height compensation probe on the conveyor belt to compensate for the height change of the material. Therefore, the moisture meter can be used in any occasion. When the microwave penetrates the material to be tested, the accuracy of the distance probe is very high, so that the best test results can be given with the least cost.
