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： The measuring sensor, particularly a lambda probe, has a ceramic sensor member retained at a high temperature during measuring operation. It is shielded from water droplets, carried along in the gas to be analyzed, by a heated protective housing, permeable for the gas to be analyzed, by which water droplets carried along in the direction of the sensor member are evaporated before reaching the sensor member. In this way, the water droplets are unable to cause any shock-like temperature drops at spots on the surface of the sensor member or material flaking.

摘要： A seal arrangement for a sensing element of a gas sensor, in particular for determining the oxygen content in exhaust gases of internal combustion engines, includes a packet made up of several seal elements, packed one on top of another, which immobilize the sensing element in a longitudinal bore of a metallic probe housing. A funnel-shaped diversion element lying in the axial direction of the sensor is integrated into the seal elements packed one above another in such a way that gas permeability between the diversion element and the inner wall of the probe housing is ensured. Toward the measured-gas end of the sensor, a small gap remains open between the sensing element and the diversion element.

摘要： To retain a plate-like sensing element, for example made of ceramic, in position within a metallic housing without danger of breakage or loosening under conditions of vibrations or shock or wide swings of temperature and substantial temperature gradients, a metallic housing has a longitudinal opening wherein in which two sealing elements are located, for example made of aluminum oxide. The sealing elements are formed, each, with an internal pocket, for example extending conically outwardly towards their meeting surfaces, to form a chamber. The chamber is filled with a resiliently compressible powder or pulverized material, for example talcum, and separates the elements by a gap (31) extending outwardly to the walls of the metallic housing. The sensor element is passed through slits formed in the end regions of the sealing elements (26, 27) and is retained in position by the compressible powder or pulverized material. The sealing elements are retained in resiliently compressed condition, towards each other, by a spring (14, 14'), for example a washer or dish-spring, held in position and exerting direct (FIG. 1) or indirect (FIG. 4) pressure tending to compress the powdery or pulverized substance (28) surrounding the portion of the sensing element (15) therebetween, and located in said chamber. Strain-relief connections can be made to terminal portions (25) of conductive tracks (24) extending along the major surfaces of the sensing element by passing end portions of spring wire clips (FIGS. 4, 6) through suitably aligned holes or grooves in a contact guide sleeve (42).

摘要： To provide an easily manufactured and easily connected heater element for a tubular ion-conductive body (26) forming a sensing element (24) of the oxygen sensor, the heater element (35) comprises a plate-like substrate (36) of insulating material, e.g. ceramic, which, at its inner end is wider than at the end fitting into the inside of the tubular ion-conductive body, the conductors leading to the heater being formed as conductive tracks spaced apart from each other by a greater distance at the inner end, adjacent connection zones (37/3), than close to the heater zone (37/1), the plate-like substrate, at the inner portion, being essentially trapezoidal and terminating in an end edge (36') which forms the wider side of the trapezoid. Electrical connection to the connection zones (37/3) and simultaneous retention of the plate-like body (36) within the sensor, are obtained by engaging the connection zones with bent-over hook-like spring wires (58, 59) pressing the plate-like body in the region of the connection zones against an abutment surface (55) formed within an insulator (40) located in the sensor.

摘要： A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

摘要： A sensor for measuring a physical property of a measuring gas, in particular the oxygen concentration or the temperature in the exhaust gas of an internal combustion engine in a motor vehicle, has a housing, a measuring element whose end section protrudes from the housing, a connector plug mounted on the end section, and a housing shell covering the end section and connector plug with a radial clearance, one shell end of the housing shell being attached to the housing and the other shell end being sealed. To prevent electromechanical breakage in the sensor in the event of extreme vibration stresses or accelerations of the vehicle, the free space within the housing shell is completely filled with a non-conductive granulate.
