Used in Manufacturing and Process Industry to measure or feed Bulk Material at desired Gravimetric Rates on a continuous basis, the equipment is provided with a set of Precision Load Cell Mounted Idlers which measure the weight of the material on the belt, dynamically, over a weighing zone. The signal is then transmitted through one Junction Box to the Microprocessor based Weigh Feeder Controller. The Controller provides output signal of the actual feed rate and also controls the speed of the belt to maintain the target value. One Rotary Speed Encoder fitted on the Drive Drum gives the actual speed value as a feed back to the Weigh Feeder Controller. The speed of the belt is continuously changed by the output signals of the controller to one Variable Voltage Variable Frequency (VVVF) Inverter Drive, which maintains the speed of the belt for maintaining the Drive Output. Optional data print out is available from the Weigh Feeder Controller. To obtain the cumulative weight of the product conveyed over the given period of time, the Controller has provisions of registering in memory for 21 (3X7) shifts, the total production with Field adjustable shifts timing and clock.
