Thermocouple, extension and compensating cable
In many industrial installations, thermocouples are located some distance from the control and measurement instrumentation, requiring the thermocouple signal to be transmitted over longer distances. Extension and compensating cables provide a practical and cost-effective way to extend the thermocouple circuit while maintaining measurement accuracy.
Kamet supplies thermocouple cables in thermocouple, extension and compensating grades, with both solid and stranded conductors available to suit different installation and application requirements.

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 similarly to a thermocouple. Insulation and jacket, by ceramic fibre, glass-fibre, 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, silicone 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, silicone 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.

Quality, service, and customisation
Kamet has partnered with various European extension cable manufacturers. Through our partnership we are able to offer customised 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.
Customised thermocouple (extension) cable allows for a variety of design options. These include flexibility, miniaturisation, single- and multicore constructions and/or ribbon, flat, coaxial or spiral style cable constructions. Each of these offers 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.
