摘要： A meander-shaped layer of nickel is deposited by evaporation on a ceramic wafer over an intermediate layer of tantalum serving to improve adhesion, and covered by a protective coating of silicon or epoxy resin is used as a temperature sensor in the intake pipe of a supercharged internal combustion engine. The low mass of the sensor element thus provided enables the resistance of the nickel path to follow rapidly, by its variation, the variations of temperature of the intake air. The sensor has a casing made up of two parts, the lower one of which has two connection prongs molded into it, the ends of which are flattened into tabs that are soldered to contact areas of the ceramic wafer. The upper casing portion has a cavity for the ceramic wafer, the lower part of which is filled with a potting compound to protect the solder joints. The width of the nickel paths that provide the temperature sensitive resistance is about 50 .mu.m and the thickness is from 0.2 to 1 .mu.m and the resistance may be typically 1000 ohms.

摘要： A circuit arrangement for transmitting variable measurement values, such as pressure and temperature, at vehicle wheels is provided which transmits the measurement values in the form of H-F signals to a stationary evaluating circuit (12) with great accuracy, high reliability and in short time intervals. A repeater coil (b 13), which is connected with the latter, arranged in the vicinity of the wheel so as to be stationary and connected to voltage by a square-wave generator (15), cooperates with a revolving repeated coil (19) which is fastened at the vehicle wheel and connected with a sensor circuit arrangement (20) supplied by it. The sensor circuit arrangement (20) contains a timing element (29) which responds to a voltage peak in the revolving repeater coil (19 l) at the end of a voltage pulse of the square-wave generator (15) and, with a corresponding delay, triggers a timing circuit (30) for transmitting the measurement values, which timing circuit (30) is connected with it on the output side, wherein the delay time of the timing element (29), together with the duty cycle of the timing circuit (30), is shorter than the pause time of the square-wave voltage at the square-wave generator (15).
