Moisture Analyzer "MT-SCAN"

MT-SCAN measures the moisture content with multi-wavelength infrared light, which is targeted to, and reflected by, the material surface; the reflected beam is measured and analysed. In other words, a certain wavelength of infrared light is absorbed by water molecules, thus more or less weakened. The weakened signal is compared to the 100 %-signal. The resulting values indicate  the moisture content.

Measuring can also be effected through glass. The moisture is monitored at different spots within the production process, which exhibits valuable information for the optimisation of the process.

Function:

• continuous non-contact moisture metering by using infrared light
• particles, fibres or other bulk goods can be measured

Locations:

• ex particle/fibre dryer
• before or after the blender
• in the forming line
• on a mat

Options:

• software for the visualisation
• Ethernet, Devicenet, Profibus
• display over interfaces 4...20 mA
• scavenging air port
• cooling system for measuring head
