Product catalog summary

Product Overview
The DF-MMA series microwave moisture analyzers, produced by Dandong Dongfang Measurement & Control Technology Co., Ltd., are advanced non-contact moisture detection devices. They are designed for online material moisture measurement and are available in two models: DF-MMA I and DF-MMA II. These analyzers are adaptable to various environments and can handle complex material shapes, high-speed operations, and corrosive conditions. They are based on an ARM platform and provide real-time, accurate moisture data for industrial process control.

Working Principle
The analyzers operate by measuring changes in microwave transmission speed and intensity as microwaves pass through materials. Moisture in materials slows down the transmission speed and weakens the intensity, allowing the device to calculate moisture content accurately.

Product Features

Contactless measurement with minimal maintenance.
Rapid, real-time results with microsecond response speed.
Fully-automatic operation with user-friendly interface.
Easy installation and debugging with various configurations.
Safe, pollution-free, and reliable without radioactive sources.
Wide application range for various substances.

Performance Indexes
DF-MMA I: Suitable for materials like coal powder, with a measuring range of 0%-50%, accuracy of 0.5%, and a thickness range of 0mm to 400mm. It operates in temperatures from -20℃ to 60℃ and has a power supply requirement of 180 to 250V AC.
DF-MMA II: Suitable for materials like acetate fiber tow bags, with a measuring range of 0%-50%, accuracy of 0.3%, and a thickness range of 0mm to 2,000mm. It shares similar environmental and power requirements as DF-MMA I.

Product Composition
DF-MMA I: Comprises measuring equipment with microwave antennas and a control system housed in a stainless steel case, featuring a user-friendly interface and IP65 standard protection.
DF-MMA II: Includes a microwave antenna rack and control system within an electric control cabinet, allowing angle adjustments for optimal testing.

Applications
The DF-MMA series is used in various industries for process improvement, dust control, quality control, and more. It is effective for non-conductors like coal, wood, sugar, and chemicals. The analyzers have been successfully applied in industries such as coal blending and acetate fiber production, demonstrating significant economic benefits.

DFMC Microwave moisture meter | DF-MMA-2

Working Principle When the microwave passes through materials with water or dry materials, the microwave will show different changes in the transmission spend and intensity along the transmission direction. The material with water will make the transmission speed of microwave slow but the intensity weak. The measurement principle of this equipment is to calculate the moisture content in the materials by testing the changes of these two kinds of physical natures of microwave after it passes through the material.
