F1 Exhaust gas temperature sensor


MST-20332 – F1 exhaust gas thermocouple type “K”, NiCr-Ni, Cl. 1

This sensor for measuring exhaust gases was developed together with a Formula 1 team. The goal was to achieve the greatest possible reliability during the race. The sensor was designed so that it can withstand a maximum of vibrations and extreme temperatures while being made in a highly compact construction at the same time. The special feature is the connection lead. It is not made from the usual mineral-insulated stainless steel sheathed line, which is too rigid and which tends to vibration fractures. Instead, the line is made of stranded conductors with PTFE insulation and an additional heat shield so it can be easily and flexibly adapted to the environment. The sensor is being used with exceeding success by professional teams in long distance races, American race series and the domestic DTM.

The benefits:

  • Highly vibration-proof
  • Very robust
  • High temperature resistance (up to 1,200 °C)
  • Individual plug assembly possible
  • Can be individually adapted
