METHOD AND DEVICE FOR DETECTING THE PASSAGE OF LUMINOUS OBJECTS SUCH AS MOLTEN METAL, AND USE SUCH DEVICE |
摘要 |
<p>In a method for detecting luminous objects, an image is formed on a zone (10) between two planes by means of a light source (241). An image is then formed of the luminous object and the light from the image is converted to an electrical quantity which is transmitted as functional information. The device comprises an optical light detection system comprising an adjustable focus lens, a photoelectric transducer (3), a converter (2), a comparator (5), a buffer stage (6), a power supply (7) and a light source (241). Application in detecting jets of molten metal.</p> |
