The ultimate intrinsically safe alignment system

ROTALIGN smart EX - The ultimate intrinsically safe alignment system

The laser alignment system for ATEX/IECEX keeps its promises under any circumstances


  • System and case fully certified for potentially explosive areas.
  • Alignment of all types of rotating machines and shafts.
  • Hundreds of positions are automatically measured during shaft rotation (SWEEP).
  • Live Move: live monitoring of horizontal and vertical corrections at any angular sensor position on the shaft. Only one measurement required for full machine adjustments.
  • Save PDF reports directly to USB memory key: no PC required.
  • Modular system: standard version is extendable to include powerful options to handle increased alignment requirements
  • Optional: Wireless data transfer using the ATEX/IECEx certified Bluetooth module. 



ROTALIGN smart RS5 EX -  The ultimate laser shaft alignment system for ATEX / IECEx

ROTALIGN smart RS5 EX is the ultimate laser shaft alignment system designed for use in potentially explosive atmospheres in accordance with ATEX and IECEx regulations. It comes in a robust light-aluminum case which is certified, too.

The system is fully packed with powerful capabilities. With the Live Move mode, only one measurement is required to perform the required machine adjustments: no matter the position of the sensor on the shaft, Live Move enables to concurrently monitor the vertical and horizontal machine corrections live on the screen. This is extremely useful in case of restricted access to predefined shaft positions.

PDF reports can be generated and directly saved from the system onto a USB key.

The optional wireless Bluetooth module is certified ATEX/IECEx, too. It allows wireless data transmission from the sensor to the computer. This is a unique capability of PRUFTECHNIK alignment systems for hazardous areas.

Our alignment software is used for preparing, analyzing, archiving measurement files and printing professional reports.
