Infrared Thermocouples
OS36 Series
No Thermal Mass Errors
No Moving Parts
Self-Powered with No Internal or External Power Requirements
No Frictional Heat Errors for Moving Surfaces
Temperature Compensated
Use with Standard Thermocouple Indicators and Controllers
The unique OS36 IR t/c™ brings together the economical thermocouple with the advantages of non-contact temperature measurement. The OS36 produces a thermocouple output signal that can be used with any standard J, K, T or E thermocouple instrumentation. The thermocouple’s accuracy is specified for target emissivity between 0.8 and 1.0. For other emissivity values, readings can be corrected to provide accurate measurements. Even without correction, the readings are extremely repeatable, for use in process and quality control applications.

* Specify temperature range code from range chart at right.
# Specify calibration, J,K,E,T. Kit includes one unit for each range (6 total) of one thermocouple calibration. Note: standard unit configuration is stripped leads. To order with GMP subminiature low-noise thermocouple connector pair, add sufffix “-GMP” to model no., and add $12 to price. To order with GST standard size low-noise thermocouple connector pair, add sufffix “-GST” to model no., and add $12 to price.
Ordering Example: OS36-J-140F-GMP
IR t/c sensor, type J, with 80 to 180°F range, GMP low-noise subminiature connectors, $185 + 12 = $197.



Right Angle Models To order with right angle view, for use in difficult to view applications change model no. from “OS36” to “OS36-RA”, and add $26 to price.
Ordering Example: OS36-RA-K-240F IR t/c, type K, 95 to 130°C range, right angle view, stripped lead termination, $185 + 26 = $211.
