Linear Incremental Encoders
An encoder is is any device or method used to translate information from one format to another. In the case of machinery systems, encoders are typically used to convert transducer signals measure position and orientation to a signal that is sent to a processed by a control system. Incremental encoders are used in conditions where the position can be reported relative to the last known position and a fixed reference position is not necessary. In a linear incremental encoder, the position is measured from a linear scale and the output is in the form of sine/cosine signals.
