Moisture Analyser for Conveyors

Supplier: Control Systems Technology

Accurate moisture content analysis using innovative low frequency microwave (LFM) technology.


Proven, accurate and continuous real-time measurement in a wide variety of materials

Flexible and Accurate Operation

  • Provides accurate moisture measurement for up to 30 products by storing multiple calibrations which are real-time plant switchable
  • Accuracy 0.3-0.4% (+/-1 standard deviation)
  • Continuous moisture reading with real-time bed depth compensation

Current bed depth capabilities:

  • 320 mm in Hematite fines
  • 400 mm in Goethite fines
  • 10-15% more than above in lump ore
  • 500 mm in coal
  • Accuracy 0.3-0.4% (+/-1 standard deviation)

First Moisture Analyser to work in iron ore

Do you need accurate control over:

  • shipping moisture limits?
  • dust extinction?
  • stockpile moisture content?
  • pre-process moisture levels?

Then LFM Moisture Analysers can help you

Models available

LFM Pilbara - Optimised for Iron Ore. Maximum particle size up to 300mm and moisture range typically 1-14% depending on bed depth

LFM Bowen Outloader - designed to accommodate high bed depths of coal (500mm at typical moisture contents) such as those occurring at train or ship load outs. Handles up to 30 calibrations. Typical moisture range 5-25%; higher in lignite.

LFM Bowen Standard - suitable for medium attenuation situations (typically bed depths less than 250mm) such as coal processing plants where value pricing is critical. Handles one moisture calibration

Key Design Features

  • Large dynamic range for measurement of high moisture content, thick beds or highly attenuating materials
  • True continuous moisture measurement
  • Rugged, low profile microwave antennas for easy installation and high reliability
  • High performance low frequency microwave electronics for exceptional accuracy
  • Modular field replaceable units
  • 4-20mA loop and MODbus serial interfaces
  • Very low microwave power (<1 microwatt/cm2 at the antenna (<< mobile phone))
  • On-line calibration via remote dial access to the Analyser (site sample required)
