MA-500 Moisture Analyzer
The MoistScan® MA-500 is the
world’s most popular on-belt microwave moisture analyzer.
Powered by Callidan’s MoistScan® patented microwave moisture
measurement technique, the MA-500 provides real-time information on
product moisture via a local HMI and through seamless integration with
the plants DCS.
The MA-500 outputs both analogue and digital data enabling immediate
manual process adjustment and real-time process automation. The MA-500
is typically used to control conveyor speed, resident times in dryers,
moisture dosing, moisture extraction and processing equipment.
In conjunction with mass measuring devices the MA-500 inline microwave
moisture analyzer is used in the mining & mineral processing industry
for volume reconciliation from pit to port.
Easily installed across the conveyor, the MA-500 does not interfere
with product flow.
The MoistScan® MA-500 is used extensively in the mining & mineral
processing, building product manufacturing and chemical manufacturing
industries.

| Benefits |
Features |
| •
Superior Precision and Accuracy |
• Analyzes
100% of the material on the conveyor from
top to bottom
• Uses MoistScan® patented microwave technology
which is the most popular microwave technology
on the market for measuring moisture in bulk
materials. |
| •
Belt Scale not required |
• Measures the bed depth of
the material to
compensate for mass flow rate. Other microwave
analysers often require an input from a beltweigher
or a radioactive
source |
|
• Non Contact |
•
No contact with the material |
|
• Non Nucleonic |
•
No radioactive source is required |
|
• Low Whole of Life Costs |
•
As no beltweigher or radioactive source is required
the ongoing costs associated with servicing and
regulatory compliance is minimal.
• No wearing parts
• No consumables |
|
• Easy to Install |
•
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 |
