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

• 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)
