MoistScan® MA-500HD On Belt Online Microwave Moisture Sensor
The MoistScan MA-500HD
online microwave moisture meter is typically suitable for metalliferous minerals and heavy
organic materials with high moisture content and thick bed depths. These
include alumina, bauxite, nickel, zinc, lead and copper in ore and
concentrate forms.
The analyser fits to a standard belt conveyor.
The MA-500HD 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 continuous
online moisture analysis of the material as it passed between
the transmitter and detector. It has a rugged c-frame
configuration, is supplied fully assembled and is easily installed.
Standard in the MA-500HD 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-500HD 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
