RF1000 RF Moisture Analyzer

Product Details

The RF-1000 RF Moisture Meter uses radio frequency electromagnetic wave technology to measure the core moisture and surface moisture content of substances. It can be used in many processes, including: the production or storage of coal, grain, fertilizer, plastic particles, food and other products. Online moisture measurement. The company also focuses on food moisture meters, feed moisture meters, etc.


The RF-1000 moisture measurement system is especially suitable for installation on the silo, hopper and conveying pipeline, belt conveyor, screw feeder and other locations for online moisture measurement of batch production processes or storage locations.

Measuring principle: According to different materials and its properties, the sensor probe can reach a measuring depth of about 15mm to 100mm. The total moisture of the product, which is the core moisture and surface moisture of the material, will be measured and analyzed. It is superior to the optical principle and only measures the surface moisture of the material. Sometimes the surface moisture is not the true value. The sensor has high penetration, so the dirt accumulated on the surface of the material does not affect the measurement. The change of the dielectric constant or relative dielectric constant of each material is an important measurement principle (RF electromagnetic wave). In order to better understand the working principle, the following is a very simple explanation: the relative permittivity of water is about εr = 80, and most other materials are about εr = 1-10. For example, the gravel εr value is between 3-4. This means that there is a large measurable difference between the relative dielectric constant εr of water (80) and the material being measured (1-10). According to this difference, the moisture value of the relevant materials can be directly measured. Then output the standard signal 0-20mA with a mass percentage of the material moisture content as a value. In other words: the more water or moisture is contained in the material, the closer the relative dielectric constant εr is to 80. On-line real-time measurement, the measurement signal can be obtained when the material passes the sensor, even if it is flowing fast On the production line, the measurement of static solid materials is also possible.

technical parameter

Sensor installation

Installed on the measuring window or isolation layer

For most applications, the product needs to be in direct contact with the sensor surface. In some applications, this may not be possible / inappropriate. Here, you can use a neutral isolation layer made of Plexiglas, glass or similar materials, placed between the sensor and the product. Can not use metal isolation layer, the maximum thickness of the isolation layer material is 30mm.
