FIELD: physics. ^ SUBSTANCE: apparatus for investigating kinematic viscosity of melts has a viscosimetric module in an evacuated or water-cooled chamber, along the axis of which a suspension system with a crucible is placed in the heating zone of an electric heater. The apparatus also has a suspension system accelerating unit, an accelerating unit switch, a mirror, a light source, a photodetector and a computer. The device also includes a visual and audio signalling unit, having at least one visual and one audio signalling device, a counter with a display. The input bus of the visual and audio signalling unit is connected to one of the computer ports. The input of the counter with a display and the computer are connected to the output bus of the visual and audio signalling unit, and the acceleration unit switch is also connected to one of the computer ports. ^ EFFECT: simplification and optimisation of the procedure of measuring viscosity, while cutting the measurement time and reducing wastes from melt components while maintaining reliability and accuracy of determining amplitude-time parameters of damping torsional vibrations of the crucible with the melt. ^ 3 cl, 5 dwg |
