LONGTEC Zhizao has independently developed a new high-end technology product based on years of experience data for various industry working conditions. The RF5000 online directional variable frequency microwave moisture meter is suitable for working conditions where the material color is very dark, the absorbance is strong, the measurement accuracy is greatly reduced by infrared optical methods, or the material moisture itself is uneven, and the results of measuring only the surface moisture of the material have no reference value. The microwave moisture meter emits microwave energy from the lower microwave transmitter and receives microwave energy from the upper microwave receiving module. By measuring the attenuation effect and phase change of the material on the microwave energy, combined with data models and special algorithms, the moisture value and density of the tested material are calculated, and the total moisture of the material is then measured.

Feature

Continuous measurement, online dynamic real-time detection

Advantage

• Real time online measurement of internal moisture in materials
• Provide historical moisture measurement data query function
• Not sensitive to the pH value and conductivity of the tested material
• Non contact measurement, will not adhere to materials, will not affect the production process
• Low emission energy, will not change the properties of the material, safe and reliable
• Not affected by environmental dust, water vapor and other factors, strong anti-interference ability
• Not affected by material color changes and sunlight exposure

• Real time transmission of 4-20mA, RS485 signals, connected to central control systems such as PLC and DCS
  

Application field

The online directional frequency conversion microwave moisture measuring instrument is suitable for online measurement of moisture content of granular, fibrous, powdery, flaky and other materials in industries such as steel, coal, tobacco, papermaking, wood, and food.
