Cement Plant Chooses Non Contact Radar Level Transmitter To Measure Granular Materials

The non contact radar level transmitter is an advanced radar-type level measurement device capable of measuring distances up to 120 meters. Its antenna has been further optimized and paired with a new fast microprocessor to achieve higher-speed signal analysis and processing. Therefore, the cement plant radar level meter is very suitable for solid materials, process containers or situations where strong dust is prone to crystallization and condensation. occasion.

In cement plants, the raw materials are mainly granular materials, and there are also a small amount of lump materials, such as limestone, raw coal, shale, etc. Semi-finished clinker is also a granular material and is stored in warehouses. These materials have repose angles and reflective interfaces on their surfaces. Depending on the material feeding and unloading conditions and surface conditions, it is crucial to select a suitable cement plant radar level meter. It is recommended to use a non contact radar level transmitter, that is, a level gauge with a rod or horn antenna, to avoid excessive pull-down force on the cable and thus avoid accidents. According to feedback from cement plants, horn-shaped antenna level gauges have stronger echoes and higher accuracy.

Cement plants and grinding stations usually have 4 to 8 cement warehouses, as well as other storage facilities such as raw meal homogenization warehouses and fly ash warehouses. The materials stored in these warehouses are all powdery materials, and measuring granular materials is challenging. Since the surface of the powder in the warehouse is relatively loose, microwave reflection is difficult. Therefore, choosing a non contact radar level transmitter with a large flange and a horn antenna is a common and effective choice. This kind of radar level meter combines a cable and an antenna into one. The microwave pulse emitted by the probe propagates along the cable. When the pulse encounters the material surface, it will be reflected back. It has a measuring range of up to 120 meters and is suitable for materials with a dielectric constant ε of 1.5. It has good wear resistance and can withstand the maximum pull-down force, and can meet the testing requirements of various powder warehouses in cement plants.
