Thermocouple wire and strip

Thermocouple wire and thermocouple strip for use at temperatures up to 1260°C.  thermocouple wire is supplied with bright or oxidized surface according to standard or special EMF requirements.

Each individual arm is calibrated against platinum and the EMF values are shown on each coil or spool.

product program for thermocouples includes:

Thermocouple wire – round and flat

Thermocouple strip

Extension leads/extension cables

Compensating cables

Bunched wire

Thermocouple protection tubes

Our program also includes a bi-filar side-by-side configuration in some size ranges.

The most used thermocouple combinations

Size range

Wire:  thermocouple wire ranges from 0.05 to 8.0 mm (0.0019 to 0.315 inch). Thermocouple wire in the size range 0.0254 mm to 0.51 mm (0.001 to 0.0201 inch) can be supplied with or without an insulating coating.

Strip: Standard sizes for thermocouple strip range from thickness 0.10 to 3.0 mm (0.0039 to 0.181 inch) and width from 4 to 195 mm (0.157 to 7.68 inch).

Standards

thermocouple alloys are supplied according to the following standards shown below. Where older standards are still in use (which are not equivalent to those listed below), we can supply different EMF values upon request.
