Model 270-4
Overview
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.
Features/Benefits
- Metering Accuracy - is typically +/- 0.25 to 1% or better (error) at two sigma based upon a given number of consecutive one minute weighments
- Unique Ratiometric Digital Weight Resolver - is extremely precise, calibration and adjustment-free, and cannot be damaged by any amount of shock or overload the weighing system may experience
- Weighing Mechanism - frictionless in operation, extremely stable, ruggedly constructed and permanently calibrated
- Compact Design – requires minimal space and mounts in an in-line configuration
- Provides Total Product Confinement – completely dust-tight from inlet to outlet
- All Steel Construction - provides long-term durability with minimal maintenance requirements
