Moisture Analyzer MT-SCAN
for particles, fibres, chips, gypsum and other bulk materials
Non-contact measuring of particle and fiber moisture.
Multi-wavelength infrared light is used which is targeted to, and reflected by the material surface. A certain wavelength of infrared light is absorbed by water molecules, thus more or less weakened. The weakened signal is compared to the unweakened signal. The resulting values indicate the moisture content.
Measuring can also be effected through a glass window. If moisture is monitored at different locations within the production process, valuable information will exhibit for optimization of the process.
- After drying
- Before / after blending
- On conveyor belt
- In forming / on mat
Any mounting orientation is allowed.

(W x H x D)
Compressed air connection for air purge
By generating low over pressure in measuring tube dust contamination will be avoided.
Conversion from % O.D. in % absolute
% O.D. = % abs. x 100 / (100 - % abs.)
Conversion from % absolute in % O.D.
% abs. = % O.D. x 100 / (100 + % O.D.)

“Material Collecting Device“
A fraction of material from drop chute will be collected in the collecting tray for measurement.
After measurement the material will be blow out of the tray by compressed air purge.
After this the collecting tray again will collect the next sample for measurement.
- Protection against freezing
(ambient temperature < 0°C)

(e.g. after dryer)
- Measuring thru glass window
(e.g. silo, bin, screw conveyor)
- Temperature sensor for measurement
of product temperature.
