Measuring hydro turbines
Innovative solutions for installation,
overhaul and maintenance of hydro turbines
• Shaft static plumbness
• Shaft runout
• Thrust bearing levelness and flatness
• Bore alignment
Time-efficient measurement method
Scalable system – Services by the experts
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.
Levelling and surface flatness during assembly
A flexible system for many measurement tasks
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.
Alternatively, INCLINEO ® can also measure the levelness and
flatness of components and foundations quickly and easily,
along with straightness and orthogonality.

Bore alignment
Prolong bearing service life
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 accurately. Bearing corrections can be monitored in real-time. The
flexible modular system allows virtually all bore and shaft
diameters to be measured.
Shaft plumbness and runout
The ultimate precision for shafts
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
