摘要:
An optical displacement sensor is used to measure the rotary displacement between two shafts which rotate together. By connecting the shafts together by means of a torsion bar, the sensor may be used to measure transmitted torque. The sensor comprises first and second coaxial discs mounted on the shafts and having slots formed therein. A light source directs light through the slots onto an array of photodetectors and a data processor determines the displacement or torque from the positions on the array of images of the slot edges.
摘要(中):
光学位移传感器用于测量一起旋转的两个轴之间的旋转位移。 通过使用扭杆将轴连接在一起,传感器可用于测量传递的扭矩。 传感器包括安装在轴上的第一和第二同轴盘,并且在其中形成槽。 光源将光通过狭槽引导到光电检测器阵列上,并且数据处理器确定从槽边缘的图像阵列上的位置的位移或扭矩。
