    • A speed measuring system comprising at least one stationary speed sensor (4) for detecting a speed of a measuring body (1) rotating relative to the speed sensor (4) wherein the measuring body (1) is provided, on its periphery, with electric or magnetic discontinuities. The speed sensor (4) situated at a defined distance from the measuring body (1), reacts to the discontinuities when the measuring body (1) is moved past the speed sensor (4). The speed measuring system has, in addition, one separate distance sensor (5) for determining an actual distance (LS) and an actual change in distance between the speed sensor (4) and the measuring body (1). In an evaluation device of the speed measuring system the speed of the measuring body (1) is formed from an actual output signal of the speed sensor (4) according to an actual output signal of the distance sensor (5).
    • 一种速度测量系统,包括至少一个用于检测相对于速度传感器(4)旋转的测量体(1)的速度的固定速度传感器(4),其中测量体(1)在其周边上设置有电 或磁不连续性。 当测量体(1)移动经过速度传感器(4)时,位于距离测量体(1)一定距离的速度传感器(4)对不连续性作出反应。 此外,速度测量系统还具有用于确定实际距离(LS)的一个单独的距离传感器(5)和速度传感器(4)和测量体(1)之间的距离的实际变化。 在速度测量系统的评估装置中,测量体(1)的速度根据距离传感器(5)的实际输出信号由速度传感器(4)的实际输出信号形成。

    • A method is described for determining a rotation speed and a rotation direction of a component (2), in particular a transmission output shaft, with a sensor device (1). In the sensor device (1), as a function of a rotation speed and direction of the component (2), a first sensor signal and a second sensor signal are generated, which are phase shifted relative to one another and each of which, on reaching an upper switching threshold or a lower switching threshold in the sensor device (1), triggers a switching signal. When there are alternating, consecutive switching signals of the two sensor signals, the sensor device (1) emits a pulse signal as a function of which a variation of a sensor signal is generated, which is used to determine a rotation speed of the component (2). After a rotation direction reversal of the component (2) a pulse signal of the sensor device (1) is only generated after sensing a rotation movement of the component (2), this rotation movement of the component (2) being sensed when, in alternation, a switching signal of one sensor signal is followed by a switching signal of the other sensor signal.
    • 描述了一种用于通过传感器装置(1)确定部件(2)的转速和旋转方向,特别是传动输出轴的方法。 在传感器装置(1)中,根据部件(2)的旋转速度和方向的函数,产生第一传感器信号和第二传感器信号,其相对于彼此相移,并且每个传感器信号 在传感器装置(1)中达到上切换阈值或较低切换阈值时,触发切换信号。 当两个传感器信号有交替的,连续的切换信号时,传感器装置(1)发出一个脉冲信号,作为其产生传感器信号的变化的函数,其用于确定部件的转速( 2)。 在组件(2)的旋转方向反转之后,传感器装置(1)的脉冲信号仅在感测到部件(2)的旋转运动之后才产生,当在(2)中检测到组件(2)的旋转运动时, 交替,一个传感器信号的切换信号后面是另一个传感器信号的切换信号。
