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

    measuring principle

    microwave-transmission measurement:

    The measured material is transmitted

    with microwaves.

    attenuation and phase shifl caused by the material is determined

    microwave
