MA500 Standard Model HDi

Intelligent moisture measurement for the iron ore industry

Principle of operation

The MoistScan® MA-500HDi online microwave moisture analyser is purpose engineered for the iron ore industry. It is suitable for iron ore concentrates, filter cake, pellets and sinter blends.

The MA-500HDi incorporates the MoistScan® patented microwave moisture measurement technique with NFA® (near field analysis) technology. The MA-500HDi is highly responsive to subtle changes in moisture. It is a proven performer on hematite. The moisture detector may also be suitable for measuring moisture in magnetite ores however this is highly application dependent, please speak to our factory for assessment of your magnetite application.

The MA-500HDi fits to a standard belt conveyor such that the microwave transmitter is located below the belt and the detector is located above the material. This enables real time moisture determination of the material as it passes through the measurement zone.

The rugged C-frame configuration is supplied fully assembled and is easily installed. The control enclosure with the industrial touch screen interface can be mounted on the C-frame as standard. Alternatively, a remote mounting option is available on request, which allows the interface to be mounted further away from the C-frame installation, e.g. control room or electrical switch room.

The user-friendly interface puts the power of easy set up and maintenance in the hands of the operator, designed with simple-to-use menus. The MA-500HDi also features built in data storage and communication capabilities enabling technical support via remote access for diagnostic purposes and periodic calibration verification. In addition, sending and receiving plant data has never been easier with a host of industry standard protocols to choose from.

Key Feature #1

Superior Precision and Accuracy; contactless measurement of 100% of product bed conveyed.

Key Feature #2

No conveyor belt scale required due to built-in material bed depth measurement with compensation for rapidly varying loads, without the use of a radioactive source.

Key Feature #3

Industry 4.0 IoT Remote Access for periodic calibration checks and servicing. Personnel don’t need to access the plant improving safety and productivity.


Key Feature #4

Seamless control system integration with a wide range of optional serial communication protocols to choose from.

Key Feature #5

Simple installation requiring only four bolts to mount the analyser to braces perpendicular across the conveyor structure.


Key Feature #6

The analyser interface consists of a built-in industrial colour touch screen with user-friendly intuitive menu’s requiring very little training to operate and powerful diagnostics.
