These electrical temperature sensors are produced following the designs of DIN 43772 and are used in machines, systems and apparatus engineering.

Other versions are also available on request (different dimensions, materials, thermocouples)

On request, also available with internationally recognised UKAS certificate

The measuring procedure of thermocouples utilises the effect that a temperature dependent tension develops at the junction between two different metals. This tension is known as thermo-electromotive voltage and increases as the temperature increases in the case of all thermocouples.

The entire temperature sensor is generally described as a thermocouple. The actual measuring element, the so called thermocouple pair, is formed from the two different conductors (+ and - poles), the thermocouple wires.


  • Comparatively small design
  • Some have a greater temperature range
  • Can be less sensitive to mechanical loads


The standards IEC 584 resp. EN 60584, define the requirements for thermocouples.

In particular, the temperature dependent thermo-electromotive voltages are defined, as well as deviation limits and to some extent the material composition of thermocouple wires.

The following thermocouples are standardized and defined:

  • Cu-CuNi (T) Copper-Constantan
  • Fe-CuNi (J) Iron-Constantan
  • NiCr-CuNi (E) Chromel-Constantan
  • NiCr-Ni (K) Chromel-Alumel
  • NiCrSi-NiSi (N) Nicrosil-Nisil
  • Pt10Rh-Pt (S) PlatinumRhodium-Platinum
  • Pt13Rh-PtĀ® PlatinumRhodium-Platinum
  • Pt30Rh-Pt6Rh(B) PlatinumRhodium-Platinum.
