Machine Positional Change–Measuring Application

LUDECA launched the ROTALIGN Ultra Live Trend, a short-term continuous-monitoring application that helps to accurately determine the relative positional changes between coupled machines during run-up or shutdown. It utilizes the unique ROTALIGN five-axis sensor to monitor continuously, in real time and simultaneously, both the vertical and horizontal parallel and angular displacement of rotating machinery, from cold to hot conditions or vice versa. By applying these measured values, the machines can be precisely aligned to reflect normal operating conditions.

The application could help lower operating costs of rotating machines by aligning them correctly with real coupling target values, because, as LUDECA notes, target values recommended by manufacturers do not always reflect the real machine centerline movements due to thermal growth, pipe strain, and dynamic factors.
