Overview
The online microwave moisture analyzer is a moisture meter that combines low-frequency microwave and mass compensation technology. This moisture meter has the ability to penetrate materials, is suitable for detecting the moisture content of solid materials, and has high anti-interference ability.
Product Details
Online microwave moisture analyzerUsing 2.40GHz low-frequency microwave (which can penetrate high-density and wide belts), the attenuation and phase change caused by the transmission of this wave through the measured medium are mainly determined by the dielectric constant and dielectric loss tangent of the medium. Water is a polar molecule, and its dielectric constant and dielectric loss tangent are higher than those of ordinary media. Usually, the dielectric constant and loss tangent of an aqueous medium are mainly determined by its moisture content. Microwaves emit energy from the microwave emitting probe located below the conveyor belt, and after passing through the belt and material, the remaining microwave energy is received by the microwave receiving probe at the upper end of the belt. Based on the attenuation of microwave power and changes in phase shift, as well as the calculation of instantaneous total mass using ultrasonic quality compensation probes, the moisture content of the material is calculated using the percentage content of total energy loss and total mass.
Due to the penetration of microwaves through the tested material, all physical moisture can be measured. This applies not only to surface moisture, but also to internal moisture! This technology improves measurement accuracy and precision, and the color and surface structure of the material, as well as water vapor and dust, will not affect the measurement results.
Advantages and Characteristics:
Not sensitive to the pH value and conductivity of the tested material.
The measurement is representative of the total water (the sum of external and internal water of the tested material) test results.
Non contact measurement: Will not wear the probe, will not adhere to materials, and will not affect the production process.
Provide instantaneous measurement values (real-time testing) for process control.
High measurement accuracy, with a uniform material accuracy of 0.1 to 0.01%.
Maintenance free and low operating costs.
Low emission energy, will not change the properties of the material, safe and reliable.
Not affected by environmental factors such as dust and water vapor, with strong anti-interference ability.
Not affected by material color changes and sunlight exposure.
Measurement method: Microwave penetration.
