Laser Camera Sensors


The intelligent digital laser and camera metal level sensor from Precimeter is a high performance laser triangulation device developed specifically for its purpose. It will measure on any molten metal surface with a surface temperature below 1000˚C.

For launder, furnace and mould
Specially designed to fit and accurately measure in different conditions
Stable performance
Built to resist metal reflectivity, harsh and smokey environments
Accurate measurement
Laser triangulation technology with precision and high resolution
Maintenance free
No calibration needed for each specific installation

The Laser Camera Sensor model ProLAD from Precimeter combines high performance laser triangulation with the necessary control functions to maintain an accurate molten metal level measurement. The 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 ProLAD sensor is especially designed for launder, furnace and mould level measurement.
