Scalable system – Services by the experts

Time-efficient measurement method

Traditional methods for the geometry measurement of hydro turbines, such as gauges and plumb lines, require time-consuming preparations. Compromises with the accuracy and repeatability of measurement results are commonly necessary.

With the ROTALIGN® Ultra laser alignment platform, PRUFTECHNIK offers a state-of-the art, versatile measurement system for the assembly and maintenance of hydro turbines. With innovative measurement methods, the system covers many requirements for turbine geometry and eliminates lengthy preparations.

Results management is also greatly simplified using the reporting function within the powerful ALIGNMENT CENTER PC software.

Alternatively, INCLINEO® can also measure the levelness and flatness of components and foundations quickly and easily, along with straightness and orthogonality.

Levelling and surface flatness during assemblyA flexible system for many measurement tasks

Time-efficient measurement method

ROTALIGN® Ultra is the platform for a wide range of applications, such as determining straightness and surface flatness, vertical alignment, rotary axial alignment and much more.

The sensors communicate wirelessly with the control unit via Bluetooth®. The self-levelling, highly accurate LEVALIGN® expert laser can be used to measure the level and flatness of large foundations and flanges with great accuracy.

Prolong bearing service life

Bore alignment

Misaligned bearings tend to distort the shaft. Significant vibration and high bearing temperatures are the result. Larger displacements will even damage the running surfaces of the bearings. This significantly reduces the efficiency of the turbine.

The CENTRALIGN® Standard application can be used to measure vertical and horizontal bores quickly and accurate-ly. Bearing corrections can be monitored in real-time. The flexible modular system allows virtually all bore and shaft diameters to be measured.

The ultimate precision for shafts

Shaft plumbness and runoutBore alignment

The ROTALIGN® Ultra Hydropower application on the ROTALIGN® Ultra platform delivers all important alignment parameters of the shaft assembly. The measurement system does not require any visual connection between the individual measuring points:

� Static vertical alignment of shafts � Runout of shafts � Levelling and surface flatness of the thrust and axial bearings

Shorter installation and overhaul time

End-to-end turbine alignment

With over 25 years of experience in developing, manufac-turing and applying laser-based measurement systems for industrial applications, PRUFTECHNIK offers a range of spe-cialized systems and services dedicated to serve the complex measurement needs in hydropower plants.

Our comprehensive worldwide sales, service and support network means that we are always close to our customers anywhere in the world.
