Abstract

Hall effect transducers were studied as an alternative to limited-wear precision potentiometers and optical encoders in measuring angular displacements. Various design parameters are identified, and the optimum Hall effect transducer configuration is presented. Using this configuration, it was possible to measure an angular rotation of 140 degrees with a standard deviation of 0.5 degrees. Within the +/- 35 degrees mid-range of the total 140 degrees, the standard deviation improved to 0.1 degrees.

研究了霍尔效应传感器，以替代有限磨损的精密电位器和光学编码器来测量角位移。确定了各种设计参数，并给出了最佳霍尔效应传感器配置。使用这种配置，可以测量140度的角旋转，标准偏差为0.5度。在140度总范围的+/- 35度中间范围内，标准偏差提高到0.1度。
