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.
