Machine alignment with the LineLazer sensors

LineLazer is a precision shaft alignment solution for use with the data analyzer Leonova Diamond® or with 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.

LineLazer alignment app

For efficient and user-friendly laser alignment of rotating equipment. The LineLazer app, designed for use with the LineLazer precision shaft alignment sensors, ensures a smoother-than-ever alignment process. The LineLazer app guides the user through the alignment process in an intuitive way. With a visually appealing interface, it provides straightforward guidance to the feet corrections necessary to achieve a perfectly aligned machine. Available for Windows, iOS, and Android devices, the LineLazer app is free to download from AppStore and Google Play.

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.

Technical overview

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. Measurement results are displayed in 100ths of millimeters or 1000ths of an inch.
