ROTALIGN Ultra iS handles with ease alignment tasks on any type of rotating machines, couplings and shafts

No matter whether it is a motor-pump set or turbomachinery trains, ROTALIGN Ultra iS is a highly versatile system made to handle alignment on all types of rotating machines.  This best-of-breed laser alignment system will save you a lot of time and effort!

With intelliSWEEP, you only get the best measurement results under any external and environmental conditions. Using a number of quality factors such as vibration and backlash, poor quality measurement points are automatically filtered out.

Live Move enables one-step machine adjustments through the simultaneous monitoring of machine corrections in both vertical and horizontal directions with the sensor at any angular position on the shaft. Not only does this save a lot of time and effort but it is also extremely useful in case of restricted access to predetermined shaft positions.

The modular system is easily configured with expert modules such as Vibration Acceptance Check, Live Trend for the monitoring of thermal growth, simultaneous multi-coupling measurement, RFID machine identification, and geometric measurements.

A class 1 Bluetooth module is integrated. PDF reports can be generated and directly saved from the system onto a USB stick. Our alignment software is used for preparing, analyzing, archiving measurement files and printing professional reports.
