摘要： A planar polarographic probe for determining the .lambda. value of gas mixtures, in particular of exhaust gases of internal combustion engines, having at least the following units: a pumping cell (A), a diffusion unit (B) with a diffusion resistance preceding a pumping electrode of the pumping cell (A) and, if necessary, a heating unit (C) is proposed in which the diffusion resistance of the diffusion unit (B) is formed by a preshaped body which becomes porous on sintering and which is inserted into the unsintered probe.Such a polarographic probe enables a sensor to be constructed in a simple manner which is particularly suitable for production, with increased reproducibility of the diffusion resistance.

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.

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.

摘要： To provide for temperature measurement of a solid electrolyte polarographic gas composition sensor, an ac signal is superimposed from an ac voltage source (2) on the applied voltage from a voltage source (1) if the sensor is a polarographic sensor, the ac signal being separated from the output by a filter combination (6, 7), the dc output being evaluated as usual, and the ac output being rectified in a rectifier (9) to obtain a measure of the temperature since the ac resistance (R.sub.alt) is highly temperature dependent (see FIG. 3). The ac preferably is about 10% of the applied dc voltage, so that the voltage swing of the ac potential falls well within the linear range of output current with respect to voltage (see FIG. 2). The output from the ac channel (7, 9) to evaluate the temperature signal can be connected to a control loop circuit (10, 11), including a heater (11) to heat the sensor to maintain a uniform temperature thereof.

摘要： To permit use of less expensive iron powder material and manufacture of more complex shapes, a mixture of iron powder, of an approximate grain size of between 30 to 450 .mu.m, and containing preferably 5 to 50% of carbonyl iron powder or from 5 to 50%, by weight, of soft ferrite powder of a grain size of from 10 to 200 .mu.m, and a thermosetting resin, in which the thermosetting resin is about 50% by volume of the overall mixture, is filled into a die. Pressure is built up in the die, which is heated, permitting excess binder to escape during the build-up phase thereof, the pressure then being held so that the resin can set in the heated die. The pressures needed are substantially less than heretofore required, in the order of from between 500 to 5000 bar.
