PROCESS DATA ACQUISITION AND EVALUATION

Measurement, analysis and display of data via VGraph VRecoS VGraph FFT Analysis VRecoS VRecoS is a system for the visualisation and recording of 3 measurement parameters, offering no statistical function (for which VGraph is available). With its neat protocols and practical print functions, it is the ideal instrument for the recording of the measurement results. VRecoS - Leaflet for download VRecoS_en.pdf (240 KB) VGraph VGraph records up to 16 measurement parameters in a production unit in parallel (such as strip thickness, strip width, strip speed, roll force, temperature, ...), evaluating them statistically. Reports available from VGraph: Variable documentations (such as a quality protocol for each manufactured coil). Decision-making support for the use of a manufactured coil (if the strip beginning is shortened by another 2 m and the strip end by 3 m, for example, the Cpk value reaches a level that allows the coil to be supplied to a more demanding customer). Diagnostic instruments, showing the strengths and weaknesses of a production unit, to recognise the suitable upgrade steps, if necessary. The VGraph office version offers a product that provides an insight into the production unit or the access to reports that have been made on remote machine processors over standard TCP/IP networks.

Our steel customers use the FFT instrument for preventive maintenance and fault finding in the mill (the wave length of the recurrent strip thickness variation indicates which roller, which roll or which bearing requires maintenance).
