Exhaust gas temperature sensors are indispensable in modern vehicles. They monitor the hot exhaust gas flow and protect components from overheating.


  • temperature range: –40 to +1,000 °C
  • high accuracy
  • short response time via thin-layer platinum resistor
  • high long-term stability
  • stainless steel housing
  • robust against mechanical, thermal and chemical strain

Typical applications include:

  • protection of temperature-sensitive components, e.g. turbocharger and all types of catalytic converter (3-way, NOx storage, SCR or diesel-oxidation catalytic converter)
  • monitoring of the free-burning process (recovery) of the diesel particulate filter
  • controlling the optimal temperature window for catalytic converters
  • measuring the EGR exhaust gas temperature as part of the on-board diagnostics (OBD)
