摘要： A resistance probe is proposed for detecting gas compositions, particularly in the exhaust gases of internal combustion engines. This resistance probe has the advantage over prior art resistance probes that, with a short response time, it is considerably more aging resistant. This is accomplished in that the resistance layer configured as a semiconductor layer is introduced or sintered into recesses or slits provided for this purpose in the prefabricated sensor carrier body and above it is applied a porous, electrically non-conductive engobe or a protective layer structure in the form of a grid or raster. These measures enable the measuring gas to gain access to the semiconductor layer, but the semiconductor layer is simultaneously protected against corrosive, erosive and/or cavitative attacks from the exhaust gas.

摘要： A sensor element for broad band sensors to determine the .lambda.-value of gas mixtures is suggested. This sensor element can be manufactured in ceramic-sheet and screen-printing technology and is provided in the diffusion gap (7) downstream from a pair of pump electrodes (8,8"), arranged on both sides of the diffusion gasp (7), with a Nernst electrode (9) which functions as an exhaust gas electrode. Due to this arrangement of the Nernst electrode (9), it is possible in a simple manner to effectively protect the pump cell formed by the interior pump electrodes (8,8') from overload and to prevent falsification of the sensor signal.

摘要： A PTC temperature sensor and a process for producing PTC temperature sensing elements from ceramic films for a PTC temperature sensor are proposed. The PTC temperature sensing elements are so designed that the PTC resistor track is hermetically encapsulated with respect to the gas being measured and the ambient air. Ceramic films based on an insulator ceramic, in particular based on Al.sub.2 O.sub.3, and ceramic films based on a solid electrolyte can be used to produce the temperature sensing elements. The PTC temperature sensor according to the invention is distinguished, in particular, by the fact that, while the manufacturing procedure is cheap, it is not subject to aging due to the effect of varying O.sub.2 partial pressures, has a high resistance to aging of the resistance characteristic in rich and lean gas mixtures, for example in motor vehicle exhaust gases, at 300.degree.-1000.degree. C. and has a construction free from extraneous potential, is characterized by short response times owning to its low heat capacity and is suitable for incorportion in very narrow housing as a consequence of small dimensions.

摘要： The NTC temperature sensor includes a NTC temperature sensing element having an NTC resistor and made of a laminated composite of ceramic films, which is so designed that the ambient air or oxygen supplied by electrolytic pumping has free access, via a channel in the laminated composite, to the NTC resistor. The NTC resistor is hermetically sealed from a gas being measured. Solid electrolyte films which conduct O.sup.-2 ions, and films based on Al.sub.2 O.sub.3 can be used to make the laminated composite. The NTC resistor characteristic curve is independent of the composition of the gas being measured. The laminated composite can be formed of at least three solid electrolyte ceramic films including a base film provided with punched-out interconnection holes and conductor tracks printed by thick film technology, an intermediate film having a punched-out channel and a channel enlargement around the ends of the conductor tracks forming the electrodes of the NTC resistor, and a covering film.

摘要： A method is disclosed for the protection of catalytic converters for exhaust gas purification by measuring the temperature with a heat tone sensor suitable particularly for the implementation of the method, wherein a heat tone sensor composed of at least two NTC or PTC resistors and provided with a coating of a catalytically active material on the sensor in the region of at least one of these resistors is arranged ahead of the catalytic converter in the exhaust gas stream or a part thereof, with the catalytically active material initiating the same exothermal reactions as they take place in the catalytic converter employed for the exhaust gas purification. If the resistor is overheated due to an overly intensive exothermal reaction, resulting in a change in resistance, the heat tone sensor detects the drop in the throughput rate of the catalytic converter.
