Acrison’s various Model 400 Series of Weigh Feeders operate on a Weight-Loss-Differential (or loss-in-weight feeding) basis; they are designed with an integral Acrison dry solids feeder, or a positive displacement liquid pump, as the metering mechanism of these precision all-digital weigh feeders, precisely controlled by an Acrison designed and manufactured advanced state-of-the-art multiprocessor controller.
Weight-Loss weigh feeders (gravimetric feeders) operate strictly on the basis of the loss of a specific amount of weight (product) in a specific amount of time. There are no other factors that enter the equation. Such weigh feeders do not utilize a zero reference as the basis for feed rate calibration; they operate strictly on the basis of weight-loss over time.
Today, it is a well accepted fact that loss-in-weight weigh feeding offers a very precise and highly dependable method for continuous metering by weight, assuming that the weigh feeder encompasses a durable, totally viable weighing system, a reliable and versatile dry solids or liquid metering mechanism, and a control system that incorporates all of the latest technologies and algorithms for optimization of performance.
In particular, the weighing system of a Weight-Loss weigh feeder, especially when operating 24/7, must remain precise, even when installed in adverse industrial environments. It cannot in any way be delicate, temperamental, and/or require frequent calibration or adjustment; it must be extremely reliable, durable and dependable. Acrison retains a clear leadership position in this critical area of weight-loss weigh feeder design, offering permanently calibrated, adjustment-free weighing systems globally recognized throughout the processing industries for their highly accurate and stable performance, for their innate ability to remain precise, and for their exceptional durability and longevity.
Acrison’s various Model 200 Series of Dry Solids Weigh Feeders are available in several different operational configurations, although they all function on the same basic principle of operation; a zero reference is utilized as the basis for feed rate calibration. The Model 200 Series of Weigh feeders are designed with an all-digital weighing and control system.
The weighing system of any weigh feeder is crucial to its performance; it cannot in any way be delicate, temperamental, require frequent calibration and/or adjustment to remain accurate. Acrison retains a leadership position in this critical area of equipment design, offering permanently calibrated and adjustment-free weighing systems globally recognized throughout the Processing Industries for their highly accurate performance capability, durability and exceptional longevity.
Acrison is the only manufacturer to offer an unconditional five (5) year guarantee on the weighing mechanisms of its weigh feeders, including the associated electronics.
