To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators. Most determine direction of rotation, speed, and angular position ...

Howard A. Schaevitz Technologies Inc. Pennsauken, N.J. Engineers continue to increase their use of linear-position and displacement sensors for providing real-time information to feedback-hungry PLCs ...

The FUTEK USB520 answers today’s challenge in industrial test and measurement environments for an all-in-one USB data-acquisition component for encoder, switchable profiles, multiple input options and ...
