Pepperl+Fuchs combines a safe evaluation unit with the advantages of the proven safePXV and WCS absolute linear positioning systems, expanding the portfolio for safe absolute positioning. The systems consisting of the safe evaluation unit (Position Unit Safe, PUS) and one safe PXV/PUS or two safe WCS/PUS read heads enable safe position and speed detection up to SIL 3 and PL e.
The evaluation unit acts as a safe gateway to the fieldbus: It processes the redundant signals from the safe PXV/PUS and safe WCS/PUS read heads, creates a safe position value, and derives a safe speed value from it. In addition to the safe and non-safe data, it also transmits diagnostic data that is available as a basis for condition monitoring and predictive maintenance. With the expanded portfolio, Pepperl+Fuchs now offers several solutions for safe and robust position detection in a wide range of applications—even in challenging environmental conditions.
