Laser Level Measurement - Review of Applications and Benefits

Level measurement prevents overfilling and dropping rocks directly on metal in the surge bin or crusher, both of which will cause damage and loss of up time. The laser beam detects the rocks level accurately, even in the presence of dust. This technology is immune from the effect of noise, vibrations, ambient air conditions, and the material angle.
