Medium
Density Fiberboard Moisture
Testing,
Measurement and Control
Having
the correct Medium Density Fiberboard moisture levels has become a critical
component during the various stages of production of MDF.
Fiber quality can be influenced by moisture
content and incorrect moisture resin addition can not only waste money
but can cause dramatic process interruptions.
Precise control of raw material fiber will
not only improve the resin addition but also provide an extra benefit of
high quality board properties.
The resin moisture addition will result
significant cost savings. The major benefit will be on the forming line
when the press will not have any down time due to blown boards, a common
result of high moisture content furnish.
With the help of industry partners and
30 years of knowledge and experience, MoistTech has developed the IR-3000
Medium Density Fiberboard Moisture Sensor that is ideally suited
to measure the moisture levels in the Medium Density Fiberboard process.
Installation….
The IR-3000 Medium
Density Fiberboard Moisture Sensor should be mounted several
inches above the conveyor will allow the user to continuously monitor the
process and can control the moisture content either manually or automatically
in the Medium Density Fiberboard process.
The unique feature of the IR-3000 is that
is able to monitor the process even with small gaps in product flow without
impacting the accuracy. Moist Tech has also developed sample systems
and optical windows using sapphire optics which will provide a viewing
area for real time process measurement.
Details of this can be seen on our section
in sampling technology.
Environment….
Dust from the product is not normally a
problem however in extreme dusty environments we recommend the installation
of an Air Purge System
to prevent the accumulation of material on the sensor’s window.
If the sensor has to be installed close to dryer outlet where it will be
susceptible to extreme heat conditions, it may be necessary to cool the
sensor with either air or water.

Your MoistTech staff is experienced with
the Medium Density Fiberboard moisture sensing requirements in the MDF
manufacturing process. Our sensor calibrations, measurement wavelengths,
algorithms and sensor optical requirements are pre-set at the factory.
Typical accuracy is about ±0.1% moisture. Typical analog range is
0-20% moisture. The outputs can be adjusted to optimize PLC or recording
requirements.
