Compensation cables : Temperature-specific measurement signal transmission with thermocompensation cables

Compensation cables compensate for temperature differences between the connection points and the reference junction without losing the thermoelectric voltage. They can also be used to interpose connecting elements (connectors). Compensation cables are made from a different thermocouple material as the thermocouple type for which they are intended. However, they do feature the same thermoelectric properties as the thermocouple type in a limited temperature range. Several compensation materials can be selected for one thermocouple type. Compensation cables are also less expensive than thermocouple cables. Compensation cables are the only option for noble metal thermocouple types S, B, and R.

To account for their use in various industries, including power plant engineering, the steel industry or furnace construction, compensation cables are insulated with different materials. In order to set them apart, the cables are labeled according to the internationally valid color code laid out in IEC 60584 Part 3. All compensation cables can be protected by braids, foils or armor. The cables are protected against electromagnetic fields thanks to their stranded design.
