Thermocouple Conductors & Color Codes

Dekoron's standard thermocouple extension cables are manufactured to the ANSI MC96.1 standard, but many other standards are available. The chart below shows the compounds and color codes on some of the most common types of thermocouple extensions and standards.

IEC allows for thermocouple extension cables to be installed in intrinsically safe systems.
In such cases, the outer jacket is blue in color, but the conductor color code is unchanged.
