Abstract: A sensor device for registering strain of a component, which comprises a sensor chip and a supporting substrate, which are connected to each other by a connecting layer such that they form a prefabricated sensor module. The sensor module is attached to the component by a durable creep-free connection such that the strain of the component is transferred to the sensor chip.

Abstract: Improving and bringing about predefined climatic conditions in the interior of a vehicle more quickly, an air mass flow rate sensor is used to measure the air mass flow rate fed to the air-conditioning system, whereby the passenger compartment can be air-conditioned quickly and effectively.

Abstract: A pressure sensor device is described that has a diaphragm acted upon by a working medium, on a first side, and a sensor chip, which is disposed on a second side of the diaphragm that is remote from the working medium. There is formed in the sensor chip a measuring bridge having four sensor elements, which form two pairs disposed parallel, and the pairs are disposed at right angles to one another. The sensor elements are disposed such that they are closely spaced apart from one another in the edge region of the sensor chip that faces toward the central point of the diaphragm.

Abstract: A capacitive measuring sensor which detects changes in an angle of electrode surfaces arranged at an acute angle to one another. The sensor outputs capacitive changes as a sensor signal. The sensor is preferably elongated and has at its end regions two fastening elements for connection to a body to be measured, two capacitor electrodes and two fastening elements. Changes in the angle of the capacitor electrodes is effected by displacement between the fastening points on the object to be measured.

Abstract: The known arrangements have at least one rotor coil (RS) arranged on the rotor and at least one stator coil (SS) arranged on the stator. The rotor coil (RS) and the stator coil (SS) respectively have at least one winding (WI) and there is a magnetic coupling between the rotor coil (RS) and the stator coil (SS). With an arrangement of this sort, it is possible for example to transmit measurement signals of a measurement pickup (MA) arranged on the rotor (RO) for the contactless measurement of torques. The additional acquisition of the respective angular position and/or of the respective angular speed (.omega.

Abstract: A capacitive force sensor is introduced between an actuator and motor vehicle brake shoe and is composed of a closed, metallic hollow cylinder that accepts a plate capacitor. One or more end faces of the hollow cylinder act as force-absorbing membranes and transmit elastic deformations onto the plate capacitor, a measured signal being generated as a result. The force sensor can be utilized in a range of measurement of up to, for example, 2.5 tons, a temperature range from -40 through 350.degree. C. and also exhibits extremely high measuring precision.

Abstract: The force or extension sensor has a measuring capacitor (Mk) whose comb-like, interlocking electrode structures (Es1, Es2) can be adjusted in parallel with one another by two attachment points (Bp1, Bp2) as a function of the force (F) or the extension (E) to be measured. The total capacitance of the measuring capacitor (Mk) is determined by a parallel circuit having individual electrode pairs. A change in the total capacitance of the measuring capacitor (Mk) which is brought about by a change in the distances (d1) between the electrodes provides information on the force (F) or the extension (.epsilon.) to be measured. A change in the distances between the electrodes as a result of temperature-related extension is at least largely avoided by virtue of the fact that the attachment points (Bp1, Bp2) lie on a junction line (V1) which runs parallel to the direction of the electrodes (E1, E2) and is oriented at an angle (.alpha.) of 40.degree. to 50.degree., preferably 45.degree.

Abstract: The force or extension sensor has a measuring capacitor (Mk) whose electrode structures (Es1, Es2), of comb-like design and interengaging, can be moved parallel to one another via two securing points (Bp1, Bp2) as a function of the force (F) to be measured or of the extension (.di-elect cons.) to be measured. The total capacitance of the measuring capacitor (Mk) is determined by parallel connection of individual electrode pairs. The variation in the total capacitance of the measuring capacitor (Mk) due to variation of the electrode separations (d1) gives information regarding the force (F) to be measured or the extension (.di-elect cons.) to be measured.

Abstract: A sensor for measuring the torque acting on a rotating shaft has two electrode structures which are respectively mechanically coupled to two axially spaced points on the shaft to be measured so that a relative movement between the two electrode structures occurs due to the torque. The electrode structures each have a number of parallel, spaced electrodes and are asymmetrically mounted in a plane so that a number of capacitors are formed by electrode pairs each having an electrode from each electrode structure. Because of the asymmetrical arrangement, the electrodes in a pair are spaced a relatively large distance away from the next closest electrode, so that a capacitive decoupling between the pairs is achieved. Changes in the spacing between the points on the shaft due to torsion of the shaft caused by the torque will change the spacing between the electrodes in each pair, thereby resulting in a total capacitance change which is proportional to the torque.
