A common problem in the processing of paper and
other material is measuring temperature in an
area where steam (water) is used. In the process of
heating/cooling, the resulting steam vapor makes
it very difficult to use non-contact infrared devices.
Since steam vapor is opaque to common infrared
wavelengths, incorrect temperatures are often
reported. In addition, condensing steam vapor on
blind to infrared wavelengths. This problem is solved
by the IRt/c air purge models in a simple and cost-
efficient fashion. The air jet from the built-in air purge
clears a path to the target material by replacing the
steam vapor in the optical path with dry air: effectively
blowing it away. Care is required in establishing the
distance to the target, and the air pressure employed,
to prevent cooling of the target area by the air jet.
