About

SPM LineLazer

Features
Read full description

The app, designed for use with the LineLazer precision shaft alignment sensors from SPM Instrument (LLS10 and LLM10), ensures a smoother-than-ever alignment process! The app guides you through the entire alignment process in an intuitive manner, using a visually appealing and intelligible 3D graphical interface. You can rotate the 3D virtual machine for a live view from any direction, and the continuous sweep function saves considerable time and effort. The app can visually amplify misalignment conditions, making it easy to see any vertical or horizontal angularity and offset. Once the system has determined the degree of misalignment, the app provides clear and straightforward on-screen guidance to the feet corrections necessary to achieve a perfectly aligned machine. Upon completion of the procedure, you can save details and results in a report that can be shared in a variety of ways. The LineLazer sensors and app are a cost-efficient laser alignment system that does not require a portable data logger. The sensors provide precise and reliable readings, and the app can be used on any laptop, tablet, or smartphone (recommended minimum screen size is 5ā€) with Bluetooth; just download the app and connect to the sensors. The app features a Demo mode, allowing users to simulate alignment scenarios and try out app functionality also without the sensors. Key features of the LineLazer app include: • Precision alignment with reliable results • Intuitive interface with enhanced, live view 3D graphics • Responsive design • Continuous sweep • Visual amplification of misalignment • Soft foot check • Feet lock • Thermal growth compensation • Tolerance checks • Demonstration mode • Free app download - no license required.
