摘要： The connection conductor leading from the connection end of a sensor element towards the end of the sensor remote from the gas to be measured is a metallic connection part (17) that is rigid against torsion and passes through the aperture (16) of the closure shell (14) where it is sealed by a bead-like element (41) having a tubular extension (48), beyond which the connection conductor has an axial internal connection surface for a cable (19). A sleeve (51) of yielding material (51) covers the adjoining ends of the cable and of the connecting conductor and an overlay shell (52) compresses the sleeve to make a tight seal, both around the cable and against the tubular end of the bead (41). The overlay shell snaps on to the tubular extension of the bead by interlocking annular sawtooth ridges.

摘要： A protective tube of metal resistant to corrosion from hot gas surrounds and is spaced from a closed-end ceramic sensor body within which is an electrical heater. The protective tube extends beyond the end of the sensor body and has an annular groove at its open end, which bulges into the space enclosed by the tube and the outer end of which provides a flange perpendicular to the axis of the tube a fine metal screen may be provided across the open end of the tube for incepting droplets of water that may sometimes be present in the gas to be measured. The open end of the protective tube may be only slightly constricted by the groove or, in another embodiment, it may taper down in a rounded fashion to a narrower opening.

摘要： A gas measurement probe has a casing (11) equipped with a closure shell (17) on its end away from the gas to be measured. At the other end of the casing, within its longitudinal bore, a sensor element (24) is held fast and tight in the casing. A rod-shaped part carrying a heater element fits within the sensor element and extends out of it at its end away from the gas to be measured to an extremity near which contact areas are provided on its periphery. On these contact areas, resilient connection wires lie under mechanical bias. These wires, between the loops bearing against the contact surface and their ends are bent in Z or sinuous shape so as to secure them against pulling, twisting and shaking forces. These connection elements and also another conductor running in the probe cooperate with an indexing feature of the rod-shaped element, such as a suitable groove to secure the rod-shaped component against twisting. This construction is particularly suitable for probes utilizing a solid electrolyte tubular sensor element closed at its tip.

摘要： To prevent signal degradation of a sensing element, which may be a potentiometric or a polarographic sensor, having a reference electrode exposed to ambient air, the reference electrode (22) is placed within a chamber (21) which has included therein granules (39) of a material inert with respect to oxygen and having a surface hardness at least as hard as the reference electrode (22) so that, upon subjection of the sensor, when coupled to the exhaust system of an internal combustion engine, to vibrations, shocks and jolts, the granules will move in the chamber, rub against the electrode, and hence keep the electrode surface activated and free from contamination which may have penetrated with ambient air.
