Thermocouple, extension and compensating cable
In some applications, a thermocouple is located in a pipeline distanced from a measuring instrument in a control center. The thermocouple signal therefore sometimes runs through an entire factory. In these cases, lower-priced material is required in order to transmit the signal from a thermocouple to a measuring instrument. The inexpensive alloys used for thermocouple compensating cables slightly differ from the actual more expensive thermocouple alloy. Kamet uses three different grades for cable: thermocouple grade, extension grade, and compensating grade. The conductors of the cables are available in 2 types: stranded and solid conductors.

Thermocouple, extension and compensating cables we offer
Kamet offers a wide range of thermocouple, extension and compensating cable for all types of applications.
- Thermocouple grade – Thermocouple grade means the alloy is exactly the same as the alloy in the temperature sensor and therefore functions similar as a thermocouple. Insulation and jacket, by ceramic fibre, glassfibre, fluoropolymer, silicone rubber, are suitable for indoor use
- Extension grade – Extension grade compensating cables have the same nominal composition of a thermocouple cable, but are calibrated as class 1 up to 200°C in accordance with DIN 43710. Insulation and jacket by fluoropolymers, silicon rubber, thermoplastic compounds, are suitable for indoor and outdoor use.
- Compensation grade – Compensating wire and strands are made of alloys that do not have to be identical to the corresponding thermocouple. Substitutive material implies nevertheless that the thermoelectric characteristics have to be the same. They are identified with the letter “C”, according to DIN IEC 60584, placed near the code letter identifying the thermocouple. Insulation and jacket by fluoropolymer, silicon rubber, thermoplastic compound, are suitable for indoor and outdoor use.
- Multi-pair thermocouple cables – Multi-pair thermocouple cables consist of groups of insulated thermocouple wires that are twisted in pairs and bundled together in the same form as multi-conductor cables.
Insulation material
Thermocouple extension and compensation cables are typically insulated with the material listed in below table. Read more about the typical insulation materials used for thermocouple extension and compensation cables.

Quality, service, and customization
Kamet has partnered with various European extension cable manufacturers. Through our partnership we are able to offer customized high performance (thermocouple) cables , contributing to a competitive advantage for even the most demanding applications.
The work we do is often project-based, making our partners in-house expertise available for the whole process from research and design to testing and production of bespoke cables with full quality control.
Customized thermocouple (extension) cable allows for a variety of design options. These include flexibility, miniaturization, single- and multicore constructions and/or ribbon, flat, coaxial or spiral style cable constructions. Each of these offer different benefits depending on the application.
A range of sheath materials can be added to create cables with excellent resistance to one or more of the following:
- chemical agents
- fire (1110°C)
- oils
- moisture
- moulds
- acids
- mechanical stress
- abrasion
- electromagnetic interference
The kinds of materials used to achieve this include Fluoropolymers, Technopolymers, Silicon Rubber, Low Smoke Zero Halogen materials and a wide range of Thermoplastics & Thermoplastic Elastomers (majority of these cables are UL/CSA approved). Furthermore, a variety of alloys may be chosen to make armoured and coaxial thermocouple cables.
We can offer an extensive range of conductor wire sizes from 0,013 mm² (7 x 0,05 mm) and up to 240 mm² in low voltage cables.
