摘要： An electrochemical measuring sensor having a solid electrolyte, a first electrode exposed to a gas to be measured and a second electrode exposed to a reference gas, with the electrodes preferably being arranged on opposite sides of the solid electrolyte. At least one of the electrodes (16, 20) is provided with a contouring (24) on its side (22) that is exposed to the gas to be measured or to the reference gas, with the contouring being a trench-shaped groove (26) embossed into the surface of the electrode such that the electrode is pressed into the adjacent solid electrolyte in the region of the groove. According to the method, the embossing is done while the electrode and the solid electrolyte are in the non-sintered state, and the sensor is subsequently sintered.

摘要： A planar polarographic sensor for determining the lambda value of gas mixtures, for use with exhaust gases in internal combustion engines, includes a planar ceramic carrier sheet having an outer pumping electrode and an inner pumping electrode respectively arranged on opposite planar sides thereof, and a diffusion barrier. The outer and inner pumping electrodes, and the diffusion barrier are arranged on the planar ceramic carrier sheet so that the measuring gas is fed via the diffusion barrier to the inner pumping electrode. The sensor has front and side edge faces. The diffusion barrier is configured as a diffusion layer at least partially covering the inner pumping electrode and exposed at least at one edge face of the sensor to the measuring gas. A diffusion-free planar region of the sensor is provided with an equalizing layer having the same thickness as the diffusion layer, and the equalizing layer is disposed in the same plane with and adjacent to the diffusion layer.

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 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.
