Mobile system for operational benchmarking of rotating machinery -
The LMS Test.Lab 12 Channel Mobile Time Data Processing & Recording system provides a mobile solution for operational benchmarking of rotating machinery. It stores raw time data histories for offline processing, while providing comprehensive online analysis functionality. The data acquisition is conducted using a portable LMS SCADAS 305 front-end with two embedded tacho inputs, supporting 12 channels for ICP® and Voltage signals, including quasi-static parameters.

The Signature Throughput workbook writes the time histories for all channels directly to the PC hard disc. The resulting TDF-data files have no size limitations and contain all dynamic and static channels, rpm-time traces for all tacho channels and overload information for each individual channel. The many online processing and visualization formats include waterfalls and order-, frequency- and octave sections. The data acquisition can be controlled remotely through a push-button box and enlarged status displays facilitate monitoring during measurement. The time data can be validated immediately after the measurement, allowing the engineer to gain a quick overview on the whole measurement or to zoom in on details.

With the Signal Calculator, the engineer can expand the measurement with virtual time histories by recombining physical measurement channels using basic and advanced mathematical operations. These time histories are calculated automatically upon completion of the measurement and stored together with the measurement channels in the same TDF-data file, so they can be processed simultaneously during the offline throughput processing. With dedicated data validation and selection, data from different measurement runs can be organized and combined for batch processing.
