Lambda probe — The so-called lambda probe (lambda sensor) is a potentiometric oxygen - gas sensor that is used to monitor the partial pressure of oxygen po2 (oxygen concentration), e.g., in the exhaust gas of cars in order to control the air/fuel ratio that is going to the internal combustion engine. The term lambda originates from the stoichiometry number A which describes the composition of the air/fuel mixture, as follows ... [Pg.393]

Since the doped Zr02 solid electrolyte (an oxygen ion conductor) oxygen gas sensors were successfully applied in the exhaust system of almost all modern automobiles in the mid-1990s, the other gases CO, NO, and short-chain hydrocarbons have been paid attention to closely [67]. Solid electrolyte gas sensors based on potentiometric have various configurations. Three types have been classified by Weppner, depending on whether the ionic species derived from the gas in question coincides with the mobile ion (Type I), the immobile ion (Type II), or neither of them (Type III) of the solid electrolyte used [68]. [Pg.4]

Sensor performance for different applications is defined by various features of the ceramic. For example, the electrical output of most pressure sensors is dependent on the bulk piezoelectric properties of a PZT ceramic. Oxygen gas sensor performance is defined by the conductivity behavior of Zr02 ceramics, which is in turn dependent on the oxygen vacancy content of the material. The performance of still other sensors, for example, ceramic thermistors, is dependent on the grain boundary characteristics of doped BaTi03 ceramics. For humidity sensors based on NiO/ZnO, the p—n junction characteristics of the interface define sensor performance. [Pg.241]

An attempt has been made to measure oxygen concentration by using a fluorine conducting electrolyte (Yamazoe et al. 1987, Miura et al. 1987, 1989, Kuwata et al. 1984a,b). Yamazoe et al. (1987) proposed an oxygen gas sensor with a lanthanum fluoride single crystal electrolyte. Lanthanum fluoride is feasible in an aqueous environment and has been used to detect dissolved oxygen in water. [Pg.199]
