    • A device for measuring angle and angular velocity or distance and speed of a moving part is described. The device has a sensor which is or can be arranged in a stationary manner and an encoder which is or can be arranged on the moving part and, together with the sensor, generates a modulation signal to be demodulated by the sensor. For the frequency measurement which is needed to measure the angular velocity/speed, the encoder has a structure which reproduces a periodic pattern and is interrupted by at least one index area for the angle/distance measurement. In the index area, the encoder has a substitute pattern which differs from the periodic pattern by at least one physical variable which can be detected by the sensor but has a structure which also enables the frequency measurement in the index area.
    • 中描述了一种设备,用于角度和角速度或位移和移动部分速度的测量。 该装置具有一个固定的可布置或布置的传感器并且可以被布置在到或设置编码器,其产生的可动部,连同传感器是从调制信号解调的传感器。 该编码器具有周期性图案再现的结构,所述位移测量通过至少一个索引范围的角度和/必要的角速度/速度测量频率测量中断。 在索引范围中,编码器包括从由至少一个由所述传感器的物理尺寸可检测的周期性图案不同的替换模式,但有一个频率测量也使得能够在索引区域结构。
