  • Gas sensor and manufacturing method for the same
    Patent number: 6546783
    Abstract: An air side cover is attached to a proximal end of a housing so as to confine an aerial atmosphere therein. A measured gas side cover is attached to a distal end of the housing so as to confine a measured gas atmosphere therein. A glass sealing material airtightly seals a clearance between an inner surface of an insulator and an outer surface of a sensing element. A contact interface of the glass sealing material protrudes toward a proximal end of the gas sensor compared with at least an adjacent portion of the remainder of the glass sealing material. By melting and hardening a glass pellet, the sensing element is airtightly fixed in the insulator.
