PRUFTECHNIK ROTALIGN Touch Laser Shaft Alignment System

Description

PRUFTECHNIK ROTALIGN Touch Laser Shaft Alignment System – Advanced Precision Tool for Motor, Pump & Rotating Machinery Alignment

The PRUFTECHNIK ROTALIGN Touch is a professional laser shaft alignment system designed for precision alignment of motors, pumps, gearboxes, compressors, turbines and other rotating machinery.

It combines PRUFTECHNIK’s sensALIGN 7 single-laser technology with a touchscreen measuring device and advanced alignment software. The system is designed for both routine shaft alignment and complex applications such as cardan shafts, vertical machines, thermal growth, machine trains and multiple couplings.

The ROTALIGN Touch also supports connectivity and cloud-based data management through PRUFTECHNIK’s ALIGNMENT RELIABILITY CENTER 4.0, allowing alignment results and work orders to be transferred between field devices and PC software.

Key Features

sensALIGN 7 Single-Laser Technology
The ROTALIGN Touch uses sensALIGN 7 laser and sensor technology. Its single-laser configuration is designed to improve repeatability and simplify setup, including eliminating the need for conventional pre-alignment.

The sensor incorporates a large 2-axis position-sensitive detector (PSD) and MEMS inclinometer technology.

Active Situational Intelligence
The system uses intelligent measurement functions including intelliSWEEP, intelliPOINT and intelliPASS to help identify poor measurement data caused by factors such as backlash, vibration or inconsistent shaft rotation.

Advanced Alignment
The ROTALIGN Touch can handle demanding applications including:
Horizontal shaft alignment
Vertical machine alignment
Soft foot
Cardan shaft alignment
Thermal growth
Machine movement
Uncoupled shaft alignment
Multi-coupling alignment
Machine-train alignment

PRUFTECHNIK’s current documentation states that the ROTALIGN Touch platform can align up to 14 machines in a machine train, depending on configuration/software.

Applications

The PRUFTECHNIK ROTALIGN Touch is suitable for:
Electric motor alignment
Pump alignment
Compressor alignment
Gearbox alignment
Generator alignment
Turbine alignment
Fan and blower alignment
Machine-train alignment
Cardan shaft alignment
Vertical machine alignment
Industrial machinery installation

Predictive maintenance
Rotating machinery maintenance

PRUFTECHNIK specifically highlights applications ranging from standard motor-pump systems to large steam turbines and complex machine trains.

Machine-Train Alignment
One of the major advantages of the ROTALIGN Touch is its ability to work with multiple machines and couplings.

This makes it appropriate for complex equipment trains rather than only simple motor-to-pump arrangements. Current PRUFTECHNIK information specifies support for machine-train alignment of up to 14 machines on the ROTALIGN Touch platform.

Cardan Shaft Alignment
The ROTALIGN Touch supports in-situ cardan shaft alignment, allowing alignment work on cardan/driveshaft applications without requiring conventional disassembly in appropriate configurations.

Soft Foot Measurement
The system includes a Soft Foot function to help technicians identify machine-foot conditions that could affect final shaft alignment.

Live Move & Live Trend
The ROTALIGN Touch provides advanced functions such as:
Live Move
Move Simulator
Live Trend
Simultaneous horizontal and vertical correction
Thermal growth monitoring

These features are particularly useful when aligning machines where positional changes need to be monitored during operation or correction.

Cloud Connectivity
The ROTALIGN Touch was designed with cloud connectivity as part of its workflow.

Through PRUFTECHNIK’s ALIGNMENT RELIABILITY CENTER 4.0, alignment work orders and measurement results can be transferred between field devices and PC software for reporting, monitoring and archiving.
