The
OS1553-A 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 is remotely mounted 4' 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-A 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.
