Measurement principle:

The contact microwave moisture meter adopts the principle of high capacitance wave penetration. The difference in dielectric constant or relative dielectric constant of each material can be used to directly measure the dielectric constant of the relevant material and calculate the water content. Then use the moisture content of the material as a standard signal based on the mass percentage as a value(0-20mAor0-10VDC)Output. The relative dielectric constant of water, εr=80Left and right, most other materials are about=1-10between. For example, gravel εrValue in3-4between. There is a significant difference in dielectric constant between water and water(80)And being measured(1-10)The relative dielectric constant of the material, εrThe higher the water or humidity content in the material, the higher its relative dielectric constant εrThe closer the value is to80The easier it is to measure. Whether it is the tested material on a fast flowing production line or a stationary tested material, as long as the material passes through the sensor probe, ε can be measuredrBy measuring the signal, the moisture measurement value can be calculated. According to different materials and their properties, the sensor probe can achieve approximately150mmto200mmMeasure depth. The moisture measured and analyzed is the total moisture, which includes the core moisture and surface moisture of the tested material. The microwave principle measures the internal and external moisture of materials, which is superior to the optical principle for measuring the surface moisture of materials. Sometimes, the surface moisture may not be the true value. The sensor probe has high penetration, so the accumulation of dirt on the surface of the material will not affect the measurement results.
