At present, very industries and manufacturing units. In this article we advanced inclinometers like ACCELENS (ACS) from will be discussing / comparing the similarities and the POSITAL use cutting edge MEMS technology for differences between single-turn rotary encoders and measurement. inclinometers based on their applications. A basic misconception was that inclinometers cannot Encoders have evolved over time from simple measure a full turn in the range of 0 - 359.99° like incremental to more complex and very precise multi- single turn encoders. But, the advances in turn absolute encoders. The technology also has technology have made that po
