Gain insights into machinery health with alignment data

Asset photo in Alignment Reliability Center 4.0 Software by PRUFTECHNIK

ALIGNMENT RELIABILITY CENTER 4.0 (ARC 4.0) is the central Windows-based software platform for managing machine measurement data. It is well-suite for large companies with decentralized sites, maintenance teams and services companies.

Using ARC 4.0, companies can map and manage entire plants. A library of customizable templates for assets, couplings, tolerances and reports and the automatic input of the appropriate measurement mode based on the bearing type minimize the risk of error during measurement. The graphical interface is so intuitive and user-friendly that managing and analyzing measurements is a breeze.

ARC 4.0 is much more than pure logging of the individual measurement results. All measurements performed are available at any time for every asset as measurement history (trend) and as detailed reports for analysis. Based on the trend curve, the maintenance manager gains useful insights into the health of their assets to identify the root cause of a misalignment condition or to precisely diagnose machinery issues.

The PC-software is suitable for all PRUFTECHNIK alignment systems. It supports data exchange via USB, Bluetooth and Wi-Fi depending on the measurement device.
