Abstract: An exhaust gas temperature sensor is described which includes first, second and third thermocouples connected in parallel to measure the gas temperature at the first, second and third penetration depths in an exhaust passage. In a preferred embodiment of the present invention, an exhaust temperature sensor mounted in a turbine passage including an inner and outer wall includes a first thermocouple located between approximately 26 percent and 30 percent of the distance from the outer wall to the inner wall. A second thermocouple is located between approximately 58 percent and 62 percent of the distance between the outer and inner passage walls. A third thermocouple is located between approximately 68 percent and 72 percent of the distance between the inner and outer passage walls.
