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.

Measuring hydro turbines

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.

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 runout

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 axialbearings
