Product information

The Laser Camera Sensor model ProH from Precimeter combines high performance laser triangulation with the necessary control functions to maintain an accurate molten metal level measurement. The patented digital camera technology in the Precimeter sensors results in very high performance and resolution. The advanced technology enables stable readings even when the molten metal material reflectivity changes dramatically and/or in harsh conditions with heavy steam and smoke environment. The built in PI controller eliminates the need for an external industrial controller.The ProH TwinDelta sensor is, amongst other applications, very suitable in slab casting applications for mould level control.

Principle

The sensor measures the difference between the edge of the mold and the molten metal surface. This means that the calibration is maintained and the level of the molten metal is absolute correct.
