The OS1562 and OS1572 are
stand-alone fiber optic infrared
sensor for applications requiring
the advantages of non-contact
temperature measurement and
fiber optic technology. They are
used where conventional infrared
detectors are not possible, such as
with targets which are not easy to
access, have small spot sizes, are
in high energy fields or are in
environments with high humidity
or containing smoke, or in
vacuum applications.
Some important factors that
determine the fiber optic assembly
needed with the sensors are: the
distance from the fiber optic probe
lens to the surface being measured;
the size of object; the temperature
range; the ambient temperature
range around the fiber optics; the
length of fiber optic cable; the
method of heating the surface being
measured; and the atmospheric
conditions between the fiber optic
lens and the product.
The ordering matrix shows a few
configurations of the sensors with
fiber optic probe assemblies.
Consult OMEGA for other available
fiber optic assembly configurations.
All systems include sensor, fiber
optic probe, and fiber optic cable.
