OPT-PROFILE is a system for the real-time measurement of the liquid metal level in aluminum casting. The sensor beams a blue laser line on top of the liquid metal bath and level is then calculated based on laser triangulation. Furthermore, a dedicated processing algorithm enables to extract the elevation profile of the liquid bath along the laser line, providing the real-time profile of the surface.
The OPT-PROFILE system provides safe and reliable control of the liquid metal level, enabling automated control of the ingot-filling process and eliminating the need for direct human intervention in hazardous areas for visual inspection. A dedicated installation analysis is performed by Ergolines specialists in order to evaluate sensor installation according to customer requirements.
