    摘要: A sensor is provided, in particular a gas sensor for determining the concentration of a gas component in a measuring gas, which has a sensor element that projects from a housing by a measuring-gas-side end section exposed to the measuring gas, and a sheath tube having gas passageways, which is placed over the measuring-gas-side end section and affixed on the housing. To prevent condensation of water vapor contained in the measuring gas in the measuring space enclosed by the housing and the sheath tube, and thus the production of water droplets that reach the hot sensor element, sheath tube and/or sensor element are/is thermally decoupled from the housing. The thermal decoupling is produced using, for instance, a flange sleeve made of a material having poor thermal conductivity, which separates the sheath tube from the housing by a flange and, via a sleeve section, is inserted in the space between the housing and the measuring-gas-side end section of the sensor element.

    摘要: An electrochemical sensor for determining the oxygen content of gases of internal combustion engines includes a ceramic element that is inserted with a sealing ring into a housing. The sealing ring is built up from different metal layers. The arrangement of the metal layers proceeds from a metal support which is composed of a steel alloy. The sealing ring is covered on both sides with a roll-clad copper layer. A nickel layer can additionally be arranged beneath the copper layer.

    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.
