For many types of continuous web production
processing, such as paper, printing, photographic
film, textiles, etc., an important parameter for quality
and throughput rate is knowledge of the point at
which ‘dryout’ occurs. More important even than
the absolute temperature, the location of this point
provides a highly precise indication of the rate of
heat input into the product, and allows direct control
of the energy input to force the dry-out point to a
specific spot in the drying process.
The IRt/c is particularly well suited to this application
due to its small size, low cost, outstanding speed,
hermetically sealed construction, and its intrinsically
safe character.
Connected to inexpensive multi-channel thermo-
couple input cards for PLCs or computers, the dry-out
point is easily calculated by the intersection of the
slopes of the temperature vs. position data provided
by the IRt/cs..

due to its small size, low cost, oustanding speed,
