Online moisture analyzer Introduction: (online, non-contact, real-time measurement of the moisture content of solid materials) in tobacco, wood (fiberboard, particleboard), chemicals (detergents, soap powder, fertilizers), paper, chemical fiber, food (rapeseed , cereals, feed, cotton, tea, food (flour, starch, milk powder, soybean meal), metallurgy (quartz sand, cement) and other industrial sectors require rapid and continuous on-line determination and control of solid materials. Water volume and material moisture are one of the most common and important monitoring and control parameters. The "digital on-line moisture measuring instrument" integrates the sensor and digital signal processing, and uses the LED digital panel to directly display the percentage moisture content of the solid material. The moisture analyzer made by using the principle of spectral absorption has the following characteristics compared with other instruments for measuring moisture: 1. The non-contact measurement has no influence on the transmission line and does not cause troubles to the operation. 2. Continuously measure the moisture content of moving and stationary materials, especially suitable for on-line monitoring. 3, can not only determine the moisture, but also output signals for record, and can form an automatic feedback control system. 4, the instrument uses a sealed structure, can work in a dusty environment, easy to install, easy to use. 5, using digital circuits for signal processing, long-term stable work. Technical Features Moisture Test Range: 0∽50% 1. Safety: Insulation resistance> 500MΩ 2. Accuracy: 0.2% 3. Repeatability: 0.1% 4. Stability: Calibration every 180 days 5. Operating Temperature Range: 0∽+40°C 6. Damping: Users can self-adjust 7 sampling times, output signal: RS485 8. Power supply: 220V10% 50Hz 9. Power consumption: 50W Working principle The working principle of moisture meter is based on Beer-Lambert law. That is, there is a certain relationship between the intensity of light reflected by the solid material and the concentration of moisture in the solid material. The energy absorbed by the water molecules increases with the increase of the moisture concentration content, and the light radiation reflected from the solid material. Energy decreases as absorption increases. The moisture meter can determine the moisture content of a solid material (static measurement) in a laboratory, and can also measure the moisture content (dynamic measurement) of a solid material on-line in a workshop.
