The system offers high-performance alignment features to perform shaft alignment with minimal time and resources. ROTALIGN smart RS5 EX usability and user guidance make alignment easy. The PRUFTECHNIK unique SWEEP measurement mode and the Live Move function greatly facilitate all alignment jobs.

The system may easily be upgraded to include advanced alignment features such as thermal growth, spacer coupling and cardan shaft alignment, or the ALIGNMENT RELIABILITY CENTER 4.0 PC software for better management and analysis of measurement data. The optional Bluetooth module is ATEX/IECEx certified and guarantees a safe wireless sensor to computer communication in ex-protected industrial areas.

sensALIGN 5

sensALIGN Series technology is based on PRUFTECHNIK single-laser technology and provides highly precise measurement results with the easiest mounting and measuring in the field.

sensALIGN 5 sensors include two HD large position sensitive detectors (PSD) and MEMS inclinometers. Combined with detector extension capability (InfiniRange), it is always possible to measure and document the initial alignment condition, no matter how big the misalignment.

The technology also allows the simultaneous monitoring of machine corrections in vertical and horizontal directions, starting from any angular position where the sensor comes to stop.
