Amphenol Advanced Sensors Exhaust Gas High-Temperature Sensor

Amphenol Advanced Sensors Exhaust Gas High-Temperature Sensor operates over a temperature range from -40°C to +850°C and withstands short excursions to +1000°C. This device monitors the temperature before and after the Selective Catalytic Reduction (SCR) system in the diesel engines as part of the engine control strategy. The sensor offers a fast response time, long-term stability, and high 3% accuracy. It is optimized for thermal dissipation and highly resistant to corrosive exhaust gases. Amphenol Exhaust Gas High-Temperature Sensor is suitable for high vibration and corrosive environments.
