A mindblowing laser alignment experience

3D display animations, capacitive touchscreen and wizard-like guidance make the alignment experience as intuitive as using a tablet or smartphone. Powered by the unique PRUFTECHNIK single laser bi-detector technology sensALIGN 7 featuring the intelliSWEEP measurement mode, ROTALIGN touch offers a horizontal and vertical move simulator and simultaneous Live Move for single or multi-coupling measurement (up to 6 couplings simultaneously).

The device is made for maximum durability in extreme working conditions. It is IP65 waterproof and dust-proof, dirt, scratch and temperature resistant. It is also fully shock and impact tested.

ROTALIGN touch is the first laser alignment tool fully designed to meet the requirements of industrial IoT with RFID, Wi-Fi and cloud data transfer.

With the ALIGNMENT RELIABILITY CENTER 4.0 software, work orders may be sent via the cloud to a mobile ROTALIGN touch unit anywhere in the world and measurement results are sent back straight from the unit into the alignment software for monitoring and advanced reporting. Asset-specific work orders and RFID machine identification make it possible to track the alignment condition of individual assets over time (alignment trend) making alignment data a dynamic condition monitoring parameter for asset management and condition-based maintenance programs.

The integrated camera enables visual asset and job documentation making the alignment job even easier the next time. Voice control frees up both your hands when the alignment job really gets hands-on. The functionality may even be operated with Bluetooth headsets in noisy machine halls.


The sensALIGN Series technology is based on the inherent PRUFTECHNIK single-laser technology providing highly precise measurement results and easiest mounting and measuring in the field. sensALIGN 7 sensors include two HD large position sensitive detectors (PSD) and MEMS inclinometers. Combined with the detector extension capability (InfiniRange), it is always possible to measure and document the initial alignment condition; no matter how big is the misalignment. Furthermore, this technology allows the simultaneous monitoring of the machine corrections in vertical and horizontal directions, starting from any angular position where the sensor comes to stop.

With sensALIGN 7, the door to the toughest alignment applications opens wide. Intelligent alignment features make it possible to approach complex alignments with serenity: intelliSWEEP filters out any poor measurement data due to difficult measuring conditions.

Whether it is a cardan shaft, a vertical pump or a turbomachine train, ROTALIGN touch will not let you down. All the best intelligent features are included: vertiSWEEP, Cardan Shaft, Live Trend, Live Move, Multicoupling Measure, Move and Live Trend.

How to upgrade your firmware?

ROTALIGN touch - ALI 50.200 computer upgrade procedure

  • Please ensure ROTALIGN touch computer is charged or has at least 50% battery capacity.

  • Unzip file to empty PRUFTECHNIK USB memory stick. Firmware is stored in "ROTALIGNtouch" folder.

  • Switch on ROTALIGN touch computer. Wait for Home screen to appear.

  • Connect USB memory stick to ROTALIGN touch computer USB port. New firmware copied from USB memory stick to ROTALIGN touch computer.

  • After approximately 1 minute on-screen message box appears stating new upgrade firmware found. Tap green tick button to start upgrade. Remove USB memory stick from ROTALIGN touch computer.

  • ROTALIGN touch computer restarts and firmware upgrade begins.

  • After completion of firmware upgrade ROTALIGN touch computer restarts and finishes in Home screen.

Voice App enables the voice control of ROTALIGN touch

Via the PRUFTECHNIK ROTALIGN touch Voice App you can easily control the ROTALIGN touch laser-shaft- and machine-alignment system due to voice control connected with your mobile phone or tablet-pc based on a Bluetooth connection. Thus you can fully concentrate on measuring and dictate the machine dimension directly into the device without even touching it. Measuring modes can be switched by voice control, too. The PRUFTECHNIK ROTALIGN Voice App amends the shaft alignment process and makes it more effective. You save time, your hands are free for the alignment process and in the end you receive a precise, reliable and repeatable alignment result.
