Formula: Ni 90/Cr 10
Form: Insulated Wire
Material: Thermocouple Alloy
Commodity: Alloys
Conductor Diameter:
0.05mm
Insulation:
Polyurethane
Insulation Thickness:
0.005mm
Polyurethane-Insulated T1 Thermocouple Wire (Ni90/Cr10) combines the high-temperature sensing capability and durability of type K thermocouple-grade nickel-chromium alloy with the flexibility, abrasion resistance, and dielectric properties of polyurethane insulation. This makes it well-suited for portable temperature probes, flexible sensor arrays, and mobile industrial testing equipment. Its insulation resists mechanical wear and maintains integrity in moderately harsh chemical environments, while allowing for tight bending radii without damage. Applications include portable thermal mapping tools, field-service temperature diagnostics, and adaptable furnace monitoring systems. In research, it is used for developing flexible thermocouple assemblies, studying insulation wear under cyclic bending, and thermoelectric stability testing in mobile systems. The balance of thermal measurement precision and flexible protection ensures performance in both industrial and field research contexts.
