Portable Vibration Analyzer Collects Maintenance Data

Ludeca Inc. introduces Vibexpert II, the latest addition to the Prueftechnik family of portable route-based vibration data collectors. Vibexpert II is rugged and lightweight and combines the advantages of a rapid processor with an energy-efficient color VGA display. Enhanced with an Fmax of 51KHz and up to 102,400 lines of resolution, all machinery problems can be captured and analyzed on the Vibexpert II large color screen. The Vibexpert II Basic platform is a one-channel device that can be upgraded at any time to two individually configured channels via a special pass code. All forms of machine vibrations, bearing conditions, process data and visual inspection information can be collected and stored on the expandable Compact Flash Card (up to 8 gigabyte) for report generation or for later transfer to the Omnitrend software for further analysis, reporting and archiving. The Vibexpert II provides an icon-driven platform that offers comprehensive analysis functionality for the diagnosis of simple or very complex vibration problems. Capabilities include order spectrum, phase, cepstrum, cross-channel phase, orbits, run-up and coast-down measurements, bump test, negative averaging and more. Analysis tools, including various cursor types, machine-specific frequency markers, signal post processing, and extensive bearing databases are included for evaluating each spectrum. Alarm notifications based on ISO standards or user-defined standards are visually identified with the aid of colored LEDs. The Vibexpert II features modular functionality including dynamic field balancing, extended time waveform recording, transient data capture, UFF file export and Modal/ODS support.
