Abstract
A staged electrode carrier of an O2 sensor comprises a sensor; a detecting end carrier installed in the sensor; the detecting end carrier having a positive lead, a negative lead and a channel communicated to atmosphere; one end of the positive lead of the detecting end carrier having a positive interface exposing in the channel so as to contact the atmosphere and one end of the detecting end carrier having a negative interface exposing from an outer wall of the detecting end carrier to contact gas to be measured; and a transferring end carrier installed in the sensor having a positive lead and a negative lead. A detecting end carrier is made of zirconium oxide, and a transferring end carrier is made of Al2O3, CaO or MgO.
