摘要： To improve operation and output voltage, particularly at 400.degree. C. and less, an oxygen sensor, especially adapted to determine oxygen content of automotive exhaust gases, is constructed by utilizing two electrodes applied on a body of stabilized zirconium dioxide, for example a closed tube, by making an electrode exposed to the exhaust gases in form of a mixture of finely dispersed ceramic material and a platinum-rhodium alloy, the ceramic material being present at about 40% (by volume) and 60% (by volume) platinum-rhodium alloy of 50-94% platinum and 50-6% rhodium (by weight). The second electrode, exposed to a reference gas comprises an alloy of palladium and another noble metal in a ratio of about 19-90% (by weight) Pd and 81-10% (by weight) noble metal. This electrode may also contain up to 40% (by volume) finely dispersed ceramic material. The electrode exposed to the exhaust gases is covered with a porous coating. The electrodes can be applied as aqueous or organic solutions of soluble noble metal compounds or suspensions, colloidal suspensions, with organic solvents, and the like, and subsequent sintering.

摘要： To provide protection to the sensitive solid ion conductive electrolyte, a metal sleeve is placed to surround the electrolyte, with clearance, and formed with openings having an increasing cross-sectional area starting from the housing or socket towards the bottom of the solid electrolyte tube to provide an approximately even temperature gradient upon exposure of the element to exhaust gases, the sleeve being additionally so formed that deflection surfaces or vanes are formed internally thereof, for example by punching the openings through the sleeve as elongated slots leaving deflecting vanes, to deflect gases passing through the openings from direct impingement on the solid electrolyte tube to protect the solid electrolyte tube against impact and contamination.

摘要： To manufacture a vibration-resistant, shock-resistant electrical connection on a ceramic substrate (11) having an electrically conductive layer (12) applied to a surface (13, 19) thereof, a groove or channel-like depression (16, 20) is formed in the surface, preferably also including a through-bore (18), into which a conductor (17) is placed. The space between the conductor and the groove, the through-bore, if provided, and an extending groove at the other surface (19) of the substrate is filled with a sinterable mass (21), preferably a cermet, containing a metal which is compatible with the metal of the conductor wire (17), both for example containing platinum. As a starting material, the plate with the grooves therein is extrusion-pressed, pre-sintered at a low temperature to give it form stability, then the electrode (12) is applied, then the electrical conductor (17) and the cermet is applied and then the entire sub-assembly is fired to sintering temperature, e.g. about 1500.degree. C.; if desired, a further protective coating (22) of magnesium spinel may be plasma-sprayed on. Due to shrinkage of the ceramic components, the wire (17) will be securely held in position in the groove, and the cermet additionally forming an electrical connection between the wire and the substrate (11). For additional strain relief, the groove can be undulating (FIG. 3).

摘要： An electrochemical measuring sensor is proposed for determining the oxygen content in exhaust gases which has a base body made of an ion-conducting solid electrolyte in the form of a tube closed at one end, an inner electrode, an outer electrode disposed on the external surface of the probe block and having a conductor track on the connection side which has a covering layer, a ceramic protective layer and a metallic sealing ring for sealing the reference space from the exhaust gas space and for making an electrical contact to the housing in which the measuring sensor is to be inserted. The electrochemical covering layer covering the conductor track is brought down on the reference side of the probe block to below the metallic sealing ring and the track is formed with uncovered lateral extensions making electrical contact with the ring. This makes it possible to significantly prolong the service life of the measuring sensor.

摘要： A Lambda probe type gas sensor for use in determining the oxygen content of exhaust gases produced by an internal combustion engine includes a sensor element of the electrochemical, solid electrolyte, metallic oxide semiconductor or Lambda air-fuel ratio variety, which sensor element is arranged in a metallic housing and is contacted by connecting cables that are brought out of the metallic housing. These connecting cables are each surrounded by cable insulation that is made of PTFE (Polytetra-fluoroethylene). The surface of the cable insulation has, at least in certain areas, a gas-permeable section that allows a reference atmosphere to arrive inside the cable insulation and, from there, in the metallic housing. The gas-permeable section, on the other hand, prevents ingress of liquids such as fuel, condensed water, etc., This is achieved, for example, by an additionally applied, PTFE film that is placed over the gas-permeable section.
