    摘要： A sensor device has a quartz tuning fork and an analysis circuit arranged on a common board inside a common housing. The quartz tuning fork has its own, second housing within the common housing for acoustically decoupling the tuning fork from the analysis circuit. The second housing also has an opening for equalizing the pressure and temperature between the second housing and the rest of the common housing. The analysis circuit, which is connected via the electrical wires to the quartz tuning fork, performs linearization, signal amplification and elimination of environmental influences on the signals emitted by the quartz tuning fork. The signals processed by the analysis circuit are further transmitted via common housing's electrical contacts to external elements. Because of the physical proximity of the quartz tuning fork and the analysis circuit, interference attributable to electrical connections between the two elements is minimized. Furthermore, because the tuning fork and the analysis circuit are exposed to the same temperature, temperature-related fluctuations in the electrical signals of the tuning fork may be accurately counter-balanced by the analysis circuit.

    摘要： A piezoelectric force sensor includes a piezoelectric plate, with one electrode on each of the top and bottom sides of the plate. One of the electrodes is electrically connected via a conductor to a contact pad. In the case that the piezoelectric plate experiences breakage, the conductor is broken, and the remaining residual capacitance of the conductor and contact pad becomes so comparatively small that the breakage can be reliably detected.

    摘要： A sensor for measuring the mixture ratio of liquids, particularly of fuel mixtures, comprises a measuring cell, which has a cavity with one inlet and one outlet. The liquid is directed through the cavity, whereby regions of the inner wall of the cavity are electrically conductive and, together with at least one additional electrically conductive surface, form a capacitor, which is a component of an evaluation circuit. The measuring cell is manufactured from at least two ceramic carriers, which are connected by way of at least one connection layer to form a layer arrangement. The cavity is produced between the ceramic carriers as the result of the lack of at least one connection layer in certain regions. In each case, at least one electrode is applied, in the vicinity of the cavity, to the ceramic carrier delimiting the cavity using thick-film technology.

    摘要： A gas sensor device has a carrier plate of ceramic or glass. The carrier has apertures which leave only strips in a spiral configuration connecting a middle region of the carrier to the outer region thereof. The apertures may be mere slits separating the connection strips or they may be apertures providing larger air gaps. On each middle region so provided on the carrier a sensor element is located that has two electrodes and a sensitive layer which establishes a conducting connection between the electrodes. The electrodes and the sensitive layer are directly applied to the upper surface of the middle region. The two electrodes are comb shaped and are placed in inter-digital configuration to define a meandering gap between them. On the underside of the middle region of the carrier a heating element for the sensor element is provided and, if desired, also a temperature measuring resistance for regulating the temperature produced by a heating resistor. Conducting paths are located on the connecting strips between the middle region and the outer region of the carrier for connecting a sensor element and its heater to circuits on the outer region of the carrier plate.
