Adjustable Temperature Range Fixed IR Sensor OS37-38-Series OS37-CF and OS38-CF Models U 30° or 1°(60:1) Field of View U Built-In Air Purge U Self-Powered U Measurements to 2500°C (4500°F) OS37-CF shown actual size. Order connectors separately. The OS37-CF/OS37-60CF Model infrared thermocouples for high-emissivity targets (non-metals and coated metals) and the OS38-CF/OS38-60CF Model for low-emissivity targets (clean metals) feature an internal screw that adjusts the 2% accuracy band anywhere within the overall temperature range. All of these units use a lens to produce a minimum spot at a focal point. Models with 30° optics produce a rectangular minimum spot size in the focal plane by using a masked detector. Models with 1° (60:1) optics produce a more conventional round minimum spot size at a focal point. All models feature a built-in air purge. GMP low-noise miniature connector. Shown smaller than actual size. GST low-noise standard connector. To Order Model No. High-Emissivity Models OS37-CF-(*) OS37-60CF-(***) Low-Emissivity Models OS38-CF-(**) OS38-60CF-(***) Linear Range Selections: J, K, T, E, R, or S; adjustable over entire sensing range Output Impedance: OS37: 6 to 13 kΩ OS38: 9 to 18 kΩ Operating Ambient Temperature Range: -18 to 85°C (0 to 185°F) Air Purge: Built-in Ambient Temperature Compensation: With air flow of 1.1 SCFM (20 psig), maximum ambient is 204°C (400°F) * Specify thermocouple Type J, K, E or T. ** Specify thermocouple Type J or K. *** Specify thermocouple Type R or S. Comes complete with set of apertures and operator’s manual. Note: Stripped leads are standard. Order miniature GMP or standard GST connectors separately. Ordering Examples: OS37-60CF-R, high-emissivity sensor, 1° field of view, Type R output. OS37-CF-K, high emissivity sensor, 30° field of view, Type K output. Spectral Response 2 to 20 microns 2 to 20 microns 0.1 to 5 microns 0.1 to 5 microns † Measurement is practical beyond thermocouple table values by use of radiation laws. Polynomials available on request. Units must be adjusted for a narrow 2% accuracy range in field.
