Oxygen sensor |
摘要 |
An oxygen sensor includes an elongated planar sensing element and a lower insulator sealably mounted within a tubular shield. The sensing element extends through a central opening disposed in the lower insulator into a sensing chamber. An annular glass support bonded at an end of the insulator is in non-bonding contact with the sensing end of the sensing element. A portion of the sensing element adjacent the glass support is coated with a carbon-based ink to prevent bonding of the glass support to the sensing element. In an alternative, a metal foil support may extend between the sensing element and the glass support. The metal support includes a plurality of dimples disposed on opposing walls that extend inwardly to contact and non-bindingly support the sensing element therein.
