ABSOLUTE ENCODERS. Optimal water supply regulation without additional gear or linkage – the RIVERT and RIVERT smart absolute encoders deliver high precision angle measurements.

  1. General Details


    For almost 40 years, Rittmeyer has been developing absolute encoders that provide reliable measurements even in harsh environments. The absolute position is available immediately after power-on. Their comprehensive backwards compatibility ensures maximum investment protection: Even nearly 40-year-old predecessor devices can be migrated to the newest generation easily. Depending on the type, the encoders differ in the number of inputs and outputs and available communication interfaces.
