    摘要: A device for measuring a flowing air quantity is proposed which comprises a sensor element which is exposed to the flowing air, is constructed in thick-film technology and contains a heating film resistor (R.sub.H), which is arranged on an insulating substrate (10) and through which current flows, and a sensor film resistor (R.sub.S) which is likewise arranged on the insulating substrate (10), serves to sense the temperature of the heating film resistor (R.sub.H) and is a component of a bridge circuit. The heating film resistor (R.sub.H) and the sensor film resistor (R.sub.S), separated from one another by an intermediate film (13) which is a good conductor of heat but is electrically insulating, are accommodated in a bubble (11) which is made of ceramic material, in particular of glass ceramic, and is arched on the insulating substrate (10). The thin diaphragm (14) made of a ceramic material ensures effective thermal uncoupling of the film resistors (R.sub.H, R.sub.S) from the insulating substrate (10). Short response times are thereby achieved.

    摘要: A sensor (10) for measurement of acceleration and/or tilt of a movable object, particularly a motor vehicle, features an interior space (12) partially filled with fluid (15). Within that space, at least two heatable, temperature-sensitive electrical circuit elements are arranged so that, in a rest or initial position of the sensor, they are equally covered or wetted by the fluid. If the acceleration and tilt of the movable object are both zero, or the two cancel each other out, the sensor reading is zero. If this is not the case, the acceleration or tilt leads to a differing degree of coverage or wetting of the at least two circuit elements, and thus to a non-zero sensor reading.

    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.
