However, with new requirements of higher accuracies, faster machine speeds, and greater reliability combined with techno-logical breakthrough in the field of electronics, a variety of new designs of position transducers emerged. These transducers made it possible to know the machine position at all times, rather than waiting for a limit switch to give position indication at a predetermined point. This permitted faster machine operation and increased throughputs.
The recent technological developments have brought some improvements in the initial models. Today optical encoders and resolvers are more commonly used in industry. The magnetic and magnetoresistive encoders find applications less frequently. |
