Moisture measurement of gypsum
Continuous moisture measurement of gypsum from quarries allows product distribution
in the storage silo to be optimized according to moisture content.
Microwave technology
The Micro-Polar moisture meter provides online measurement of the moisture content of gypsum transported by a conveyor belt to the intermediary storage before the kiln.
Using microwave technology, a non-contacting measurement is made through the entire product height. This allows a representative online measurement even if the product on the belt comes from a mixture of different storage areas with different humidity levels.
Online measurement for quality improvement
Microwave measurement is non-contacting; no sensor comes into contact with the product to be measured, which limits maintenance and avoids special cleaning. The measurement is not influenced by the colour or inhomogeneity of the measured product. Furthermore, the measurement is carried out on the entire product profile while traditional measurements only measure the surface of the material profile.
In addition, the multi-frequency technique and the reference line enhance the stability and representativeness of the resulting measurement. Berthold’s Micro-Polar system is very easy to install.
The transmitter has a large display and a user-friendly interface. Automatic calibration can also be performed on site.
