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. With the use of Laser Class II, no special safety measures are required. 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.
