A moisture measuring probe was installed in a mixer floor within a few hours. Results: no build-up on sensor; less wear then with a rod probe; mixing of small small batches possible; no increase in mixing time. The moisture measurement of bulk materials is an essential part of process control in many sectors, such as the stone and earth, glass and food industries. Higher quality requirements, increased plant productivity and more efficient production processes require precise knowledge of the process parameter ”bulk material moisture”. Especially in an economically difficult environment, the process optimisations listed below can lead to a competitive advantage. Positioning of the measuring sensors Moisture measurement sensors are used in a wide variety of places depending on the system concept. Firstly, in gravimetric dosing and weighing systems, the sensors mentioned above should ensure exact net dosing of the additives. The process control system can now take the known water content into account and compensate for it during dosing and weighing. Depending on the dosing system concept, the sensors are installed on belts, in the silo or at the silo outlet. You would

The determination of product moisture in various processes has always played an important role, be it the moisture measurement of individual raw materials or the entire batch. In the manufacture of products, the exact moisture content is a decisive feature for dimensional accuracy, appearance, feel and durability in order to guarantee the desired quality of the product. Economical and resource-saving In today’s world, which is accompanied by rising energy costs, moisture measurement that is well integrated into the process helps to reduce production costs. Resource-saving handling of bulk materials is fundamental and must be aimed for. In addition, CO2 emissions can be reduced to the necessary minimum in possible drying processes. Optimal measurement under difficult conditions The dielectric microwave measuring head requires direct contact with the measured medium. The high-frequency measuring signals penetrate at least 50 mm into the material to be measured, so that even deeper medium moisture levels are accurately detected and a larger quantity of bulk material is measured. The HF power of the probe absorbed by the measured medium
