Online Directed Frequency Conversion Microwave Moisture Meter

The conventional method for measuring moisture content in materials is the oven method, which has the disadvantage of requiring a considerable amount of operation time and provides severely delayed information. Therefore, this method cannot be applied on the production line and can only be used in laboratories. The RF5000 continuous microwave moisture meter, however, can quickly and continuously measure moisture on belts or production lines, achieving online dynamic real-time detection with fast response time, thus enabling real-time control of product moisture content.

Structure and Principle

The online microwave analyzer has two modules: a transmitting module and a receiving module. The microwave transmitting module emits microwave signals through the material to the microwave receiving module. The microwave energy is emitted by the microwave transmitter and the remaining microwave energy is received by the microwave receiver after passing through the material. By measuring the attenuation of the microwave energy and changes in phase, calculating the total loss of microwave energy, and combining it with data models and special algorithms, the moisture content of the tested medium can be determined.

Core Advantages

 Measures total water (the sum of surface and internal moisture of the material), making the test results more representative.
 Non-contact measurement: does not wear out the probe, does not stick to the material, and does not affect the production process.
 High measurement accuracy, 0.2-0.5% for uniform materials.
 Maintenance-free, low operating cost.
 Low emission energy, does not change the properties of the material, safe and reliable.
 Not affected by environmental dust or water vapor, strong anti-interference ability.
 Not affected by changes in material color or sunlight exposure.
 Measurement method: microwave penetration.
 Standard configuration: microwave transmitting probe, microwave receiving probe, microcomputer central processing system.
