Laud, K R; Logothetis, E M; Park, J K

Thermistors comprising transition metal such as iron, rare earth of the lanthanide series or yttrium, and oxygen exhibit sufficient independence to variation in oxygen partial pressure over a range of exhaust gas conditions of internal combustion engines as to make them particularly suitable for temperature compensation of oxygen sensors such as those derived from titania as well as temperature sensing in other oxygen varying environments.
