With over 550 employees worldwide, Prüftechnik are world leaders in Condition Based Monitoring, Non-Destructive Testing and Laser Alignment solutions across a wide range of industrial applications.

With products, processes and services for condition monitoring and availability optimization, Prüftechnik helps to ensure that your machines run smoothly and generate an output of consistently high quality. This also includes systems for automatic process control and quality assurance that are integrated directly in your production process.



With OPTALIGN smart RS5, shaft alignment has never been so smooth. The unique RS5 sensor contains two XL HD position-sensitive detectors and a MEMS inclinometer to precisely measure the exact position of the laser beam as the shafts are rotated.

With the continuous SWEEP measurement mode, hundreds of positions are automatically measured as shafts are rotated. Measurement can start in any direction with the sensors at any position. All relevant alignment results, including soft foot, are graphically displayed on one screen.

Smiley symbols clearly indicate the alignment status. With concurrent Live Move, only one measurement is required to perform the required machine adjustments - extremely useful in case of restricted access to predefined shaft positions.

The Bluetooth module for wireless communication is included in the standard version. PDF reports can be generated easily and directly saved from the system onto a USB stick.

Use the PC software ALIGNMENT CENTER to prepare, analyze, archive measurement files and to print professional reports.

Key Features

  • Alignment of horizontal, vertical and flange-mounted machines, coupled and uncoupled shafts
  • Sensor with XL HD detectors and MEMS inclinometer
  • Hundreds of positions are automatically measured during shaft rotation - SWEEP.
  • Live monitoring of horizontal and vertical corrections at any angular sensor position on the shaft - Concurrent Live Move
  • Flip machines functionality
  • Save measurement reports as PDF onto a USB stick
  • Bluetooth module included

OPTALIGN® smart RS5 is packed with powerful functions for the alignment of horizontal, vertical and flangemounted machines. The system has been designed for industrial applications and can be used in extreme maintenance working conditions. 

Laser / Sensor 

The OPTALIGN® smart RS5 measurement ​principle is based on the patented single laser beam technology which uses one laser and a sensor including two biaxial position detectors and an electronic inclinometer.


The OPTALIGN® smart RS5 computer features a high resolution TFT colour display for clear information readability even in unfavourable light conditions. The computer is operated by disposable or Li-Ion rechargeable batteries. The USB interface enables easy connection to a PC and other peripheral devices such as a printer.

Operation and user interface  

The alphanumeric keyboard and the navigations keys ensure comfortable operation of the measurement system. With the context menu the user can easily access all required options. The status line text provides valuable guidance for beginners. The alignment results are clearly displayed in graphic and digital formats.​
