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 regulating device is proposed for the mixture composition of an internal combustion engine having a signal sensor and having regulating ranges which can be switched over between lambda equals one and the lean range. The lambda-equal-to-one regulation is effected by means of a two-point regulator and the lean regulation is effected either via an altered set-point value of the two-point regulator or with the aid of a steady regulator. The transitions between the two types of regulation take a course dependent on a selectable function, in order to avoid abrupt changes in rpm. A switchover is also made to controlled operation for a brief period at the beginning of each type of regulation.

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.
