There is several types of speed measurement, each of them having advantages & limits.
Because every installation has its specific goal and particular constraints, we offer 6 different speed measurement devices: 2 adapted to weigh belt-feeders (digital encoder on tail drum, tag inserted in between the belt plies), 4 dedicated to belt-weighers (pulses taken either on tail drum, under carrying belt, above return belt or through our EG-BS electro generator).
