Butt-Welded Unsheathed Fine Gage Microtemp Thermocouples

These Butt-Welded Unsheathed Fine-Gage Microtemp Thermocouples are designed for ultra-fast, direct temperature measurement in hard-to-access or space-constrained locations. The butt-welded junction ensures a minimal thermal mass, enabling rapid response. Without a protective sheath, they are optimized for short-life, high-precision applications—ideal where fine temperature gradients or rapid transients need to be captured. Installation typically involves fusion or weld mounting.

Key Benefits and Uses:

Extremely fast response due to minimal thermal mass

Butt-welded junction offers a true junction for accurate measurement

Unsheathed design allows direct contact with the process medium

Suitable for confined spaces, micro-environments, or fine surface temperature profiling

Common in research, material testing, or furnace control where speed matters

Calibration-ready to ensure that transient measurements are reliable
