This high performance system
allows one to view targets that
are not optically accessible with
standard line of sight
instrumentation.

This high performance emissivity
independent 2-color system
consists of a DP1541 and sensors.
The DP1541 is a single-channel,
19 inch rack mount 2-color control
system. Three sensors are
available; OS1542-L1-R1 or
OS1542-L1-R2 or OS1543-L1-R3.

The OS1543 fiber optic sensor
head has a lead sulfide detector
filtered over wide bands centered at

1.55 and 2.25 microns. It is used as
a general purpose head which can
measure temperatures down to
250°C. It should not be used where
hot steam or gas is present.

The fiber optic cable assembly
differs according to certain
parameters specific to the
application. It allows remote
mounting of the OS1542 or OS1543
detector heads away from hot or
hazardous areas.

The OS1542 and OS1543
fiber optic sensors are
designed specifically to work
with the DP1541 2-color
emissivity-independent
monitor and the associated
fiber optic cable assembly.
The small size of these
probes makes them well
suited for installations with
limited mounting room. They
are unaffected by RFI and
EMI noise, which also make
them excellent for use in
hostile environments like
induction or microwave
heating.

The OS1542 and OS1543
fiber optic sensors operate at
2 wavebands and utilize an
energy ratio to calculate
temperature. They can,
therefore, measure
temperature on objects
whose emissivity is unknown
provided the emissivity at all
temperatures is proportional
at the 2 wavebands used for
the measurement, which
is typical.

The OS1542 fiber optic
sensor head has a silicon
detector filtered at narrow
bands centered at 0.90 and

1.06 microns; it is used
primarily at high temperatures
and is minimally affected by
steam and hot gas.
