What are Thermocouple Cables?
Thermocouple cables and extension wires allow the accurate and electronic measurement of temperature and have numerous industrial applications in specialist and extreme environments.
They generally comprise two strands of conductor made of different metals, one being the positive conductor and the other the negative conductor. The two dissimilar metals in the thermocouple cable are electrically joined at the sensing point. When heated the metals produces a thermoelectric charge (Electro Motive Force, or EMF), which changes as the temperature increases or decreases. The EMF (measured in millivolts) that arises is proportional to the temperature difference between the two conductors at the sensing point.
Different temperature applications require different metal conductors, different jacketing/sheathing materials and different calibration. Thermocouple cables are therefore available in a broad range of combinations of conductor, jacketing and calibration. Each pair calibrated to suit a different temperature range and environment. The most common types are manufactured to IEC Specifications J, K, T, N and IEC colour Codes. They are also available in many other local colour codes.
The diameter of conductor used also plays an important part. Generally larger diameter conductors can withstand higher temperatures and are more durable, but have a slower response time than smaller diameter conductors.
Typically, both conductors are insulated then laid or twisted together and finally over-sheathed or over-braided.

Thermocouple cables are specifically designed for temperature measurement and control applications. They consist of two different metal wires or conductors that create a voltage difference when subjected to temperature variations. This voltage difference is used to accurately measure temperature. Thermocouple cables are engineered to withstand extreme temperatures, ranging from cryogenic conditions to high heat, making them ideal for use in extreme environments.
There are several types of thermocouple cables, each designated by a letter combination such as Type K, Type J, Type T and Type N. These types are based on the specific metal combinations used in the cables, with each type having its own temperature range and characteristics. It is important to select the appropriate type of thermocouple cable based on the temperature range and application requirements.
Yes, thermocouple cables are often used in hazardous environments where the presence of flammable gases, chemicals, or high temperatures pose a potential risk. However, it is important to select thermocouple cables that meet the specific safety requirements of your hazardous environment, such as having the appropriate certifications and ratings.
Yes, thermocouple cables can be customized to meet the specific requirements of your application. Cable manufacturers specializing in extreme environment cables can work closely with you to determine the best thermocouple cable configuration, including the conductor material, insulation type, shielding, and overall construction, to ensure optimal performance and reliability.
