Are all oxygen base sensors generally the same?
No. The base sensor design and elements vary greatly. Below is a list of the most widely used base sensors. • Single wire unheated standard zirconia sensors. • Two wire unheated standard zirconia sensors. • Three wire heated standard zirconia sensors. • Three wire heated titania sensors. • Four wire heated standard zirconia thimble type isolated ground sensors. Within this sensor group there are multiple heater types. • Four wire heated standard zirconia thimble type case ground sensors. Within this sensor group there are multiple heater types. • Four wire heated standard zirconia planar type isolated ground sensors. Within this sensor group there are multiple heater types. • Four wire heated zirconia thimble type air fuel ratio sensors. • Four wire heated zirconia planar type air fuel ratio sensors. • UEGO five wire wide air fuel ratio sensors.
