The OS1553 is a self-contained fiber
optic infrared transmitter designed to
provide a linear 4 to 20 mA output
for monitoring, datalogging or
controlling temperature.
The detector can be remotely
mounted as far as 9 m (30') away
from the fiber optic lens via the fiber
optic cable, removing it from
hazardous locations. Other problems
that can be overcome by the
OS1553’s fiber optic design include:
taking measurements in high energy
fields; measuring very small objects
or surfaces; taking measurements in
“dirty” atmospheres containing
water vapor, dust or smoke.
Some important factors that will
determine the fiber optic assembly
needed for your infrared application
are: the distance from the fiber optic
lens to the surface being measured;
the size of the object being
measured; temperature range;
ambient temperature around
the fiber optic cable; the length
of the cable; the method of heating
the surface being measured; and
the atmospheric conditions between
the fiber optic lens and product.
