PMD 2450 Precision Microwave Device
Online Microwave Moisture Measurement accuracy of up to 0,1 %
- moisture content of non- and low- conductive materials
optional: area weight compensation
- density of aqueous solutions/ Brix
- concentration of aqueous solutions
optional: compensation of air bubbles
- carbon in flyash
Advantages:
precise
highly selective on water
inline
contactless measurement of
solids directly at the existing
conveyor without extensive
mechanical sampling devices. Measurement of fluids directly
in pipes.
representative
measuring a large percentage of material due to the transmission geometry. The whole volume is analyzed,not only the surface.
application examples:
coal | minerals | iron ore | magnesite | wood chips | pulp | woodboards | gipsumboards |
steel industry | cement industry | building industry | mining | coal power station | paper industry |
chemical industry | wood industry | food industry
