Technical overview
Structure and specification.
- Outside diameter
- Ø 0.25 / 0.5 / 0.8 / 1.0 / 1.5 / 2.0 mm and other sizes
- Thermocouple types
- K / E / J / T / N / S / R / B; available combinations are model-dependent
- Sheath materials
- SUS304, SUS316, 310S, Inconel and other materials
- Protection tube references
- 304, 316L, 310S, Inconel 600, GH3039, GH3030 and Hastelloy; confirm for each model
- Measuring junction
- Grounded, ungrounded, exposed or special junction
- Connections
- High-temperature leads, compensating cable, standard or miniature connectors, and custom connections
High-temperature Type S, R and B applications generally use alumina or ceramic protection tubes; a metal-sheathed MI construction is generally not recommended directly. Confirm the available combinations of diameter, thermocouple type and sheath for each model.
Based on the revised OSK product manual. Confirm dimensions, materials, ratings and available combinations for the specific model.
