Belt Feeder Controller
Belt Feeder Controller
Belt Feeder Controller, PR446 control the feed rate from a conveyor belt fitted with a variable speed motor drive. It connects with 1 to 4 load cells fitted to the belt weigher mechanism from which it generates a calibrated weight signal. It also connects with a tacho from which it receives pulses in proportion to belt movement. From these two inputs and from calibrated and control data held in its system memory it calculates the rate of flow of material over the belt.
