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 is the only manufacturer to offer an unconditional five (5) year guarantee on the weighing mechanisms of its weigh feeders, including the associated electronics.
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.
The Model 403 Series of 'Weight-Loss-Differential' Weigh Feeders utilize Overhead type weighing systems specifically designed by Acrison for continuous or batch weighing of dry solids or liquids on a 'weight-loss' basis. Model 403 Weighing Systems are technologically advanced lever mechanisms (scales) utilizing Acrison designed and manufactured stainless steel flexures for all pivotal connections. Frictionless in operation, these performance-proven weighing systems are extremely stable, exceptionally rugged, and counter-balanced so that only the net weight of material in the metering mechanisms (and in their supply hoppers or tanks) is weighed.
The Models 402/402X and 404X/404Z Series, and the Models 405, 406, and 408 'Weight-Loss' Weigh Feeders feature a Platform type weighing system specifically designed by Acrison for continuous or batch weighing of dry solids or liquids on a weight-loss basis. The weighing systems of these particular model feeders incorporate technologically advanced, lever mechanisms (scales) utilizing Acrison designed and manufactured stainless steel flexures for all pivotal connections.
The Model 407X Weight-Loss Weigh Feeder features a uniquely configured, open platform type weighing system specifically designed by Acrison for continuous or batch weighing of dry solids on a weight-loss basis. The Model 407X Weighing System incorporates a technologically advanced lever mechanism (scale) utilizing Acrison designed and manufactured stainless steel flexures for all pivotal connections.
Smallest of Acrison’s Model 400 Series of “Weight-Loss” Weigh feeders, the Model 410-170-MI-5 has been specifically designed to accurately and dependably feed a wide variety of dry solid ingredients at the lowest possible rates. An Acrison Model 170-MI-5 Metering Mechanism mounted onto an Acrison Model 410 Weighing System, provides optimum materials-handling versatility, flexibility and highly reliable metering performance at very low feed rates.
The Model 403B(D) Series of Batch/Dump Weighing Systems utilize an Overhead type weighing system specifically designed by Acrison for batch weighing of dry solids on a Gain in Weight basis. Model 403B(D) Weighing Systems utilize technologically advanced lever mechanisms (scales) equipped with Acrison designed and manufactured stainless steel flexures for all pivotal connections. Frictionless in operation, these time-proven weighing systems are extremely stable, exceptionally rugged, and counter-balanced so that only the weight of material in the weigh hopper is weighed.
The Model 203 Series of Weigh Belt Feeders include an integral Prefeeder to feed dry solid ingredients onto a scale-mounted constant speed weigh belt where the feed output of the Prefeeder is continuously modulated so that product discharging off of the weigh belt precisely matches the feed rate selection. And like all Acrison Weigh Feeders, the control system encompasses the latest technologies and algorithms to ensure optimum performance.
Acrison’s various Model 260 Weigh Belt Weighers and Weigh Belt Feeders are precision, heavy-duty, high capacity devices designed to weigh and/or totalize the flow of dry solid materials in a Wild-Flow configuration, or to meter dry solid materials in a controlled Closed-Loop configuration as a weigh feeder.
The Model 270 Series of In-Line Weigh Feeders include an integral prefeeder to feed dry solid ingredients into a scale-mounted circular weigh chamber, housing a series of weigh pockets rotating at a constant speed. The feed output of the prefeeder is continuously modulated so that product discharging from the weigh feeder precisely matches the feed rate selection. And like all Acrison Weigh Feeders, the controller or control system encompasses the latest technologies and algorithms to ensure optimum performance.
