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.
