MoistScan® MA-500HDi On Belt Online Microwave Moisture
Analyser
The MoistScan MA-500HDi
online microwave moisture analyser is purpose-engineered for the iron ore industry. It is
suitable for iron ores, iron ore concentrates, iron ore filter cake,
iron ore 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.
The MA-500HDi fits to a standard belt conveyor.
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 burden. This enables continuous
moisture determination of the material as it passes between the
transmitter and detector. It has a rugged c-frame
configuration, is supplied fully assembled and is easily installed.
Standard are many different communication options for sending and
receiving data. Its user-friendly features are designed to assist with
commissioning & calibration. Importantly, the data storage and
communication capabilities of the MA-500HDi enable technical support via
remote access for diagnostic purposes and periodic calibration
verification.
Benefits
Features
-
Superior precision and accuracy
-
Analyses 100% of the material on the conveyor from
top to bottom.
- Uses MoistScan®,
the most widely used online microwave analysis
technology on the market for measuring moisture in
bulk materials
-
Measures the bed depth of the material to compensate
for mass flow rate. Other microwave analyses may
require an input from a beltweigher or a radioactive
source.
- No
contact with the material being analysed
- No
Radioactive source required
- As no
beltweigher or radioactive sources are required
ongoing costs associated with servicing and
regulatory compliance is minimal
- Fully
assembled and easily bolts to the stringer supports
of the conveyor
-
Seamless plant integration
- Wide
range of communication options for transmitting data
to plant PLC
-
Remote access calibration & servicing
-
Cost-effective remote communication access for
periodic checking of calibration
