Beschreibung
Zusammenfassung:	An apparatus for contact-free sensing of a moving coherent mass of material, for example a stream of molten glass, comprises first sensing means for producing first output signals for determining the speed of advance of the material past the sensing apparatus and second sensing means for producing a second output signal related to a dimension, e.g. the diameter, of the material transverse to its direction of advance. The sensing apparatus further includes optical means comprising a common objective lens for supplying radiation focussed from the material being sensed to both said first and second sensing means.
