The Loss in Weight Controller is designed to control filling by measuring the loss in weight of product from a hopper. It is ideal to use to fill bags or drums in the agricultural industry and silo weighing.
It can be used on its own or with additional control from a PLC.
Hopper replenishment and taring is performed automatically and along with in-flight compensation, final error is kept to a minimum.
On receipt of a start signal the hopper level is checked to confirm sufficient material to fulfill the preset fill value. If correct, an auto-tare occurs and the feed valve is opened until the fill value is reached. If the hopper level does not have sufficient product, however, the feed valve will not open, but the hopper fill valve will be opened until a preset high limit is reached. A preset timer allows the hopper to settle before the cycle is started. If a further start signal is received during the timeout period then the discharge cycle is initiated.
