Our IRt/cs are designed and manufactured to
provide a lifetime of reliable operation under the
most demanding service conditions. To assure this
performance, every IRt/c is put through a rigorous
process of manufacture, including seven separate
test stages. At the end of this process, the IRt/c is
ready to be installed, to provide you with many years
of reliable infrared temperature data. As an additi-
onal reliability feature, all IRt/cs are manufactured
with a Xenon gas bubble, which is hermetically
sealed into the sensing system. If the hermetic seal
is broken by mechanical or thermal damage to the
sensor, the Xenon immediately escapes, triggering
a noticeable change. Upon breakage of the seal,
the IRt/c radiation sensitivity (difference between
target and sensor temperature) immediately drops
by more than a factor of two. This signals a clear
and instant indication of sensor failure, which can
be then acted upon and a replacement quickly
installed. This method of instant alert is greatly
preferred over the alternative, since a damaged
sensor could cause poor quality output for a long
period of time before a failure is detected.
