Thermocouple Cable - KX EX TX

This thermocouple extension cable is a thermocouple cable identified by the letter X (e.g. for type K cable KX). This extension grade wire is only used to extend a thermocouple signal from a probe back to the instrument reading the signal. They are commonly used in many industrial applications such as temperature sensors in gas turbines but also have laboratory and domestic applications. The extension grade thermocouple wire typically has a lower ambient temperature limit than thermocouple, meaning it may pass a signal representing a higher temperature as received from the probe, but the wire itself may not be physically exposed to higher temperatures.

Thermocouple extension cables are paired conductors, with each conductor being made of a different material - Eland Cables' thermocouple is the most common Type K variety, where the positive conductor is Chromel alloy (abbreviated as NiCr and with green numbered insulation) and the negative is Alumel (NiAl and with white insulation). This is in accordance with the colour coding of IEC 60584-3. Other conductor combinations are available upon request. They are available as ICAM 300/500V and CAM 250V.

Other thermocouple variants are designated EX - NiCr / CuNi (Nickel Chromium / Copper Nickel) with an individual screen, and TX - Cu / Cu/Ni (Copper / Copper Nickel) available as both individual and collective screened versions with a double steel tape armour.
