TSM’s Opti-Yield family of single component Loss-in-Weight Measurement feeders offers precise measurement, total reliability, and advanced process control options to ensure consistent end product quality with optimized material usage. Throughputs from 50kg/hr (110lb/hr) to 2,000kg/hr (4,400lb/hr) are available. 

The system comprises a hopper bin mounted over a weighing hopper and allows for continuous gravimetric weighing of materials entering the process machine.  

The electronics module monitors the gravimetric weight from the high set point to the low set point within the weigh hopper. When the weigh hopper reaches the low set point, the electronics module opens the slide gate under the hopper bin and fills until high set point is reached.  

Haul off speed measurement is added to ensure that the Weight per Length is controlled to the desired specification (yield control). This ensures that the product being produced is maintained at the desired average thickness or unit weight without operator intervention. This mode can be extended to weight per area control through entry or automatic measurement of material width.
