| description | A heterogeneous transformation process taking place in a liquid, e.g. the desulphurization of steel, which produces vibrations, is monitored by detecting vibrations produced therein 1. The vibrations are subjected to spectral analysis and, in signal processing circuit 3, is divided into two frequency ranges (figures 3 and 4). The ratio of the (average) vibration amplitudes in the two frequency ranges is formed, and this enables instantaneous values for a diffusion coefficient of the transformation process to be calculated, so that the end point of the process may be determined. Automatic control of the process is also envisaged. |
