Loss In Weight System

The Jesma loss-in-weight feeder is a fully electronic weighing system, which is specially designed for continuous dosing of additives with a high dynamic accuracy incl. the critical stage of re-filling the weighing bin.

The functional principle for a LIW system is through repeated static weighing of the product bin to determine and regulate the mass flow.The product bin is slowly emptied, and the relation between the loss in weight and the speed of the discharge system gives the amount signal, which controls the dosing speed to the required value.

To achieve highest possible dynamic accuracy, the discharge system is mounted with a 2-channel incremental encoder with high signal rate which continuously monitors the speed of the discharge and signals the actual speed to the Jesma weigh controller.Through careful considerations regarding product characteristics, all Jesma loss in weight feeders are designed for highest possible dynamic accuracy, market leading operational reliability and user friendliness.
