Machine alignment with LineLazer
LineLazer is a precision shaft alignment solution used with the data analyzer Leonova Diamond or the SPM LineLazer app. This dual-laser system for quick and reliable shaft alignment is suitable for most combinations of machinery: horizontal, vertical or flange-mounted, with coupled or uncoupled shafts.
LineLazer alignment sensors
The IP65-rated alignment sensors use digital signal processing to easily and automatically distinguish from interfering light sources. High-precision digital CMOS linear image sensors provide maximum accuracy. The sensors communicate via Bluetooth, enabling hassle-free shaft alignment.
Reliable and hassle-free machine alignment
Dual-axis high-precision inclinometers measure the angle of rotation of both detector units at all times. This allows measurements in fully automatic mode, with much less than a half-turn of the shaft. The system comes with robust aluminum brackets and extendable chains for up to 480 mm (18”) diameter shafts.
The LineLazer alignment kit (together with Leonova Diamond) performs alignment calculations for horizontal as well as vertical or flange-mounted machines. Soft foot check, thermal growth compensation, and tolerance checks are built-in. The severity of the misalignment is indicated in green-yellow-red. The ‘Feet lock’ function automatically provides alternative alignment corrections, making the alignment procedure quick and easy.

LineLazer alignment app
The LineLazer app transforms shaft alignment into a seamless, user-friendly experience, perfect for aligning rotating equipment with accuracy. Designed to work with LineLazer’s high-precision shaft alignment sensors, the app offers intuitive, step-by-step guidance through the alignment process, making even complex adjustments straightforward. Its visually appealing interface features detailed 3D models, such as motor-pump and gearbox-generator assemblies, that illustrate necessary adjustments in real-time.
Available for Windows, iOS, and Android, the SPM LineLazer app is free to download from App Store and Google Play – bringing precision and convenience to your device.

Technical overview of LineLazer
The alignment sensors are identical, with the exception of the position of the laser diode and the knob for adjustment of the laser on the ‘M’ sensor. The sensors communicate wirelessly with Leonova Diamond via Bluetooth.
The alignment sensors provide maximum accuracy using a spread laser beam in combination with a 28.7 mm detector. Through digital filtering, the laser beam can be distinguished from interfering light sources. Both alignment sensors are transmitters/detectors.
The alignment sensors have dual axis high precision inclinometers that measure the angle of rotation of both alignment sensors at all times. This allows measurement in fully automatic mode, with much less than a half-turn of the shaft. Measuring results are displayed in 100ths of millimeters or 1000ths of an inch.
