摘要： A method for manufacturing a GMR bridge detector as well as the bridge detector itself in which magnetoresistive resistors are interconnected in the form of a bridge to detect a magnetic field. The resistors consist of a material that exhibits the giant magnetoresistive ratio (GMR) effect. The magnetoresistive sensitivity of the individual resistors is produced through annealing. The annealing of the resistors takes place through selective feeding of a current that is sufficient for reaching the temperature required for annealing into the bridge connections. Depending on the wiring of the bridge connections, the resistors are provided with the property necessary for the GMR effect either singly or in pairs. As the material for the resistors, in particular, a material of the class of discontinuous multilayer materials, particularly NiFe/Ag, is used in which the GMR property is produced through single annealing at a specific temperature.

摘要： A device for measuring an angle and/or the torque acting on a rotatable body is proposed according to the invention, whereby the rotational angle is detected by means of magnetic or optical sensors. In particular, in a preferred exemplary embodiment, two devices (7, 8) are proposed, each of which comprises two optically readable code tracks. The two code tracks (1a, 1b or 2a, 2b) on one device (7 or 8) are similar in design and are offset in relation to each other, so that associated sensors (4) output a digital signal. The rotational angle is calculated based on the lag between the two digital signals. In a further embodiment it is provided that a torsion element (5) having a known torsional stiffness is situated between the two devices (7, 8). Torque transferred by the rotatable body (3) can also be calculated therefore from the angular difference of the two devices 7, 8. The device is used preferably in the steering axle of a motor vehicle.

摘要： The contactless magneto-resistive angle sensing device (1) includes two sensor components (10,11) oriented at a fixed angle relative to each other, a controllable power supply (PW) to heat and maintain the sensor components (10,11) at different temperatures, a magnet (MG) producing a magnetic field (B) in which the sensor components are arranged and an evaluating device (12) to receive output signals (U1,U2) from the sensor components (10,11). Each sensor component (10,11) includes magneto-resistive resistors (MR) connected in a respective bridge (B1,B2) having input terminals (I1,I1';I2,I2') for supply of current and output terminals (O1,O1';O2,O2') for the output signal (U1,U2). In a rotating magnetic field the evaluating device (12) analyzes the output signals (U1,U2) as a function of field angle and temperature to determine a reference angle at which the output signals of the angle sensing device have a minimum temperature dependence and stores the reference angle as a zero point for subsequent angular measurements. The sensor components are then mounted on a rotatable part whose angular position is to be subsequently measured at an angular position in relation to a stationary magnetic corresponding to the reference angle.

摘要： A method and a device for measuring the angle of a rotatable body, in particular a body rotatable by more than 360.degree., are described. In this case this rotatable body cooperates with at least two further rotatable bodies, for example gear wheels, whose angular positions are determined with the aid of two sensors. The angular position of the rotatable body is determined from the angular positions detected in this way. So that unequivocal statements can be made, it is necessary for all three rotatable bodies or gear wheels to have defined predetermined numbers of teeth. The method and the device can be used, for example, for determining the steering angle of a motor vehicle.
