Thermocouple Cable - KX EX TX

Thermocouple extension cables are 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.

Thermocouple Cable Specification

Thermocouple cables are commonly used in numerous industrial applications, ranging from temperature sensors in gas turbines to 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' most commonly specific thermocouple is the 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). 

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 collective screening (CAM) and individual and collective screened (ICAM) variants and with a double steel tape armour.

Thermocouple Extension Cable Datasheets

Our technical datasheets outline the construction, standards, dimensional data, and electrical characteristics for the KX, EX and TX cable types. The identification of the cores is in accordance with the colour coding of IEC 60584-3. Other conductor combinations are available upon request.

To note: KX Cables are available as either 250V or 300/500V cables depending on thermocouple types and screening variations.
