Coal mine iron powder moisture detector trace moisture online monitoring

The online near-infrared moisture tester adopts the most advanced international three-wavelength six-beam near-infrared diffuse reflection principle, enabling rapid continuous measurement on the conveyor belt

for rapid continuous measurement of material moisture content, and non-contact with the measured material, achieving real-time dynamic monitoring of material moisture content, with a response time of only

5ms. Achieved rapid real-time monitoring and feedback of product moisture content, greatly meeting the strict requirements for moisture management in products. Due to the use of non-contact

Contact measurement method causes no damage to the measured material, thereby providing a precise and efficient solution for moisture control in the production process.

solution. 

An infrared moisture meter is an instrument that uses the principle that water molecules have strong absorption characteristics for infrared light of specific wavelengths to quickly and non-contact measure the moisture content of materials-1-4. It is widely used in industrial production lines as a real-time quality control and process optimization tool-1-5。

💡 Working principle

Its core is based on near-infrared spectroscopy technology: near-infrared light of specific wavelengths (such as1.94μm) when irradiating the material, it will be absorbed by water molecules, and the reflected light energy will be correspondingly weakened-2-4. The instrument calculates the moisture content of the material by analyzing the energy loss of the reflected light-1. Common three-wavelength or eight-beam technology can eliminate interference from non-moisture factors such as material color and structure, making the measurement more accurate-1-3。

🔍 How to choose

•  

Clarify requirements: First, determine whether it is used forOnline production lineOrLaboratory spot check. Online type needs a sturdy shell and real-time communication capability, while laboratory benchtop type focuses more on high precision and sample adaptability-9-10。

•  
•  

Evaluate materials: Different materials (such as dark powders, lump ores, transparent films) have different reflection characteristics for infrared light, and it is necessary to confirm whether the equipment can effectively measure your material-1-8。

•  
•  

Consider the environment: If the installation environment has high dust, high humidity, or high temperature, choose a model with good sealing and cooling protection functions-5-8。
