摘要： An unheated planar sensor element for determining the concentration of a gas component in a gas mixture, in particular the oxygen concentration in the exhaust gas of an internal combustion engine, has a sensor foil made of a solid electrolyte with an outer electrode exposed to the measuring gas, and an inner electrode exposed to a reference gas, as well as a reference-gas channel, which is covered by the sensor foil on one side and accommodates the inner electrode. To produce a small-volume, cost-effective unheated sensor element for use in small combustion engines having low power output yet sufficiently satisfactory measuring accuracy, the reference-gas channel is sealed on the underside by an additional sensor foil made of a solid electrolyte, and covered by an inner electrode lying inside the reference-gas channel and an outer electrode exposed to the measuring gas.

摘要： The ceramic sensor body, held inside a housing by a sealing packing, is provided with a circumferential coating of an electrically insulating material in the region of the sealing packing, so that the sensor body remains potential-free with respect to the housing, even when a sealing packing is used that is made of a material having poor electrical insulating qualities. In this manner, a glass putty is used for the sealing packing, which, while having comparatively poor insulating characteristics, provides a good sealing effect at high loading capacity.

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.
