Model 400 Series “Weight–Loss Differential” Weigh Feeders Overview
Acrison’s various Model 400 Series of Weigh Feeders operate on a ‘Weight-Loss-Differential’ 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 controller.
‘Weight-Loss’ weigh 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 the ‘Weight-Loss’ principle of operation offers a very precise and highly dependable method for continuous metering by weight, assuming that the weigh feeder encompasses a proven, 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 the typically adverse industrial environment. It cannot in any way be delicate, temperamental, and/or require frequent calibration or adjustment to maintain its ability to perform accurately; 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 is the only manufacturer to offer an unconditional five (5) year guarantee on the entire weighing mechanism of its various model weigh feeders, including the associated electronics.
