does the MCT460-WP Measure Moisture?
Water molecules contain O-H bonds which absorb light energy
in a specific region of the NIR spectrum. The more water that
is present, the greater the energy that is absorbed.
The MCT460-WP houses a
quartz halogen lamp which channels energy through a rotating
wheel containing NIR filters, one positioned at a wavelength
where water absorbs and others positioned at reference wavelengths
where there’s no absorption by water.
Pulses of light illuminate the product and the diffused reflected
light is collected by a concave mirror and focused onto a
single temperature controlled detector. Detector signals are
processed to give a read-out proportional to the concentration
of water. Resin measurements are based upon the O-H and C-H
Simple & Reliable
The MCT460-WP remains a
total hands-off gauge. Upon installation, simply adjust the
zero and put the gauge to work! There is no routine maintenance
or re-calibration. Calibration check standards are available
for confirmation of long term gauge stability.
