display (3).

Four positioning points are used for measurement. These points transfer the force to the
weighing cells installed on the corners. The glass panel made of safety glass makes sure
the force is distributed evenly on all four corners.
The scales’ display only visualizes the recorded object weight.
3 – Measurement gantry with MLG-2 light grids and wire draw encoder
The measurement gantry consists of a horizontal and vertical pair of light grids, which are
arranged at right angles. Both pairs of light grids determine the object’s contour based on
the principles of shadows.
Each pair of light grids consists of a sender unit with emitting diodes and a receiver unit
with receiving diodes.
