The MMA-2000 Microwave Moisture Analyzer System |
The MMA-2000 is the most advanced noncontacting two-parameter microwave sytem available for continuous, online monitoring of industrial material bulk properties such as moisture content (mc) and basis weight [mass per unit area]. This system is ideal for monitoring moving panels and bulk granular/particulate materials that are being transported by a conveyor or shaker, or by gravity flow in a hopper. Advanced features include: -Bulk moisture content and basis weight are measured simultaneously and independently* -Noncontacting mass transport scale* -Compensated for wave reflections at air/material interfaces* -One-way, two-way,*or four-way ("double-bounce")*through-transmission sensing -Temperature compensation -Microprocessor-based, automatic and user-friendly -Computation of complex dielectric properties* -Wide dynamic ranges of material moisture and thickness -Industrialized, user friendly packaging -Environmentally safe ___________________________________ *These features are all unique to the MMA-2000 |

MMA 2000 Control Enclosure. A sensor enclosure that contains the horn antennas and microwave electronics is separate, e.g., see photos below. |
2-Channel, "double-bounce" sensor enclosure (6 horns + microwave electronics) installed above a 5ft wide particle board caul conveyor. The conduit on the left extends to the control enclosure. Here, the MMA monitors the mat basis weights [both wet (Mtot) and dry (Md)] and moisture content [%mc]. |
1-Channel "double-bounce" MMA sensor enclosure (3 horns + microwave electronics seen at upper center ) temporarily mounted over a 5 ft wide MDF mat on a metal screen conveyor. An unrelated IR moisture gauge is also seen at lower center. The control enclosure is shown at right. Here, the MMA monitors the MDF mat basis weights [both wet (Mtot) and dry (Md)] and moisture content [%mc]. |
The control enclosure that is mounted beneath an elevated MDF metal screen conveyor is shown at top center. A monitor and keyboard are temporatily used for instrument setup. |
3-Channel "double-bounce" sensor enclosure (center) mounted above an 8 ft wide fiberglass wool mat that is conveyed by a composite belt that slides over a stationary metal reflecting plate.. The control enclosure is seen at the lower left. Moisture content at about 2% is being monitored for control of the downstream drying oven. |
%mc and Basis Weight profiles of MDF mat. Note the increase of material being put into the mat with the inverse of bulk %mc. |
Close tracking of KDC MMA (yellow) and MeasureX (dark blue) total basis weights (BW). Also shown are KDC's independly determined dry BW and bulk %mc. |
Compare KDC (Bulk) and IR (surface) moisture readings for MDF mat. Note the large variations of the IR Top Core prior and after line stops, while the KDC bulk readings are much less variable. Also, note the rapid evaporation from both the core and face surfaces (IR) than that for the bulk readings. |
