The use of incremental encoders has become indispensable in virtually all areas of industry. Its uses can be found for making simple displacement measurements on assembly lines, tool and die factories, robots, etc. Other areas include RPM measurements of rotating machinery, location and position measurements, and velocity. Found both in the sensors (incremental), as well as in the measurement modules (encoder interfaces), the signals of the incremental encoder are evaluated for substantial differences. These differences are often deciding factors on the suitability of a measurement system for the desired application. Therefore, the structure and operation of these sensors have become indispensable and the manner in which the signals in the encoder interfaces are processed and evaluated by the company, imc Meßsysteme GmbH, are discussed in this article.
