DENSO’s small exhaust gas temperature sensor quickly and accurately detects the temperature.

DENSO provides two types - standard type and high-responsive type - in accordance with responsiveness, and five types - ULs, Ls, L, Mh and H - in accordance with ability to detect temperatures ranging from - 40 degrees to 1000 degrees.

DENSO Technology – Leading the World

• In 1975, DENSO introduced the world’s first exhaust gas temperature sensor.
  
• In 1998, DENSO introduced an exhaust gas temperature sensor with the world’s highest responsiveness, enabling a feedback control of the exhaust gas temperature. The exhaust gas temperature sensor also has the world’s smallest sensing part – a more than 90 percent reduction in volume compared to DENSO’s conventional exhaust gas temperature sensor.

Benefits and Features

• Small size and high responsiveness
  
  • DENSO’s processing technique, using finer ceramic particles, produces a small specifically shaped thermistor (sensing element).
    
  • The sensing part, which is inserted into the exhaust pipe with the thermistor, has a single tube structure rather than a double-tube structure like the conventional exhaust gas temperature sensor, achieving a more than 90 percent size reduction in volume compared to the conventional exhaust gas temperature sensor.
    
  • The sensing part and the shaped thermistor enable high responsiveness – less than 7 seconds of 63 percent responding time from room temperature to 1000 degrees Celsius.
    
• High detection accuracy
  
  • The exhaust gas temperature sensor detects temperatures within ±10 degrees of the actual temperature, despite its small size
