System Description and Usage
The
SpecMetrix®
In-line coating thickness measurement system is designed to measure the thickness or
coat weight of wet or dry coatings applied to flat sheets, continuous coil or plastic film and coatings on
many other substrates. Each system is comprised of one or multiple probes connected by fiber optic
cable to a controls enclosure mounted near the coating line so that the supplied probe cables can
terminate in the controls enclosure. The probes are usually mounted between the coater and the oven
for wet coating measurement and after the oven for dry coating measurement. The enclosure has a
data connection to the
SpecMetrix®
Display Unit, which can be up to 150 feet (~50 meters) away.
SpecMetrix®
systems use proprietary ruggedized optical interference technology to measure the
absolute wet or dry coating thickness. This is a non-contact and non-destructive technology that only
requires minimal prior knowledge of the refractive Index of the coating to evaluate the coating thickness
measurement in microns. When measuring wet coatings, the dry coat weight in units such as MgSI,
Mg4SI, lbs./ream or GSM is then calculated from the wet or dry thickness using data from the coating
manufacturer such as wet density (lbs./gallon or gram/liter) and % solids by weight and %solids by
volume.
