Abstract: PROBLEM TO BE SOLVED: To detect the level of molten metal or alloy having low melting point by irradiating light from a light source such that only a part of luminous flux is shielded by the molten surface and the remainder reaches the inner wall of a container in the advancing direction of light. SOLUTION: The surface of molten metal or alloy, which does not wet the inner wall of a container, is irradiated with light from a light source such that only a part of the luminous flux is shielded by the molten surface and the remainder reaches the inner wall of a container in the advancing direction of light. Reflected light from the molten surface and the inner wall of the container is received by a camera while forming a shadow at a part where the molten surface touches the inner wall of the container and the shadow part is detected as a molten level. More specifically, the surface of molten metal or alloy supplied from a molten holding pan 1 through a molten supply nozzle 2 into a mold 3 is projected upward in the center thereof because of the wettability thereof.  When the molten surface is irradiated with light from a light source 10, a shadow part having relatively small quantity of arriving light is formed on the inner wall of the mold 3 on the side opposite to the light source 10. The shadow is picked up by a camera 11 and processed by means of a computer 12.

Filed: 1988-05-31
Abstract: PURPOSE:To detect a particle over a wide concn. range, by stepwise and automatically controlling the gain of an amplifier when the output of the amplifier received by a sensing processor reaches a preset level. CONSTITUTION:The light emitted into a detection space 1 from a light emitting element 3 is scattered by a particle 2 in a low particle concn. range and the scattering light at that time is received by a photodetector to be amplified by an amplifier 5 and subsequently received by a sensing processor 6 to be processed thereby and the concn. of the particle is transmitted to a central control unit. When the concn. of the particle increases and the output V0 of the amplifier 5 reaches a preset level, the gain of the amplifier 5 is stepwise lowered on the basis of the control signal from the sensing processor 6 through an AGC circuit 8. By this method, even when the concn. of the particle increases, the saturation of the amplifier 5 can be avoided. A data to which a code showing gain lowering quantity is applied is transmitted from the sensing processor 6 and decoded by the central control unit to determine accurate particle concn.
