MoistScan® MA-500 On Belt Online Microwave Moisture Analyser

General Description

The MoistScan MA-500 online microwave moisture analyzer is ideal for use on non-conducting materials with low to medium moisture content and relatively low bed depth.

The online moisture meter is particularly well suited for analysis of most ranks and types of coal.

The MA-500 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 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-500 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-500 enable technical support via remote access for diagnostic purposes and periodic calibration verification.


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
•    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 &
•    Cost-effective remote communication access for
      periodic checking of calibration
