Weight-Loss Weigh Feeder - Model 407X

Model 407X-170-1Model 407X-170-1


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. Frictionless in operation, this weighing system is extremely stable, rugged and counterbalanced so that only the net weight of material in the metering mechanism (and in its supply hopper) is accurately weighed. Acrison’s various controllers and control systems encompass the latest technologies and algorithms to ensure optimum levels of performance.


  • Metering Accuracy - is typically +/- 0.25 to 1% or better (error) at two sigma based on a given number of consecutive one minute weighments
  • Versatile - a range of metering mechanisms is available to effectively handle a wide range of dry solid materials
  • 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 - extremely stable, ruggedly constructed, and permanently calibrated; longevity is unsurpassed
  • Dust-Tight Construction - provides total product confinement from inlet to outlet
  • All Steel Construction - provides long-term durability with minimal maintenance requirements


  • Weighing System:
    • Technologically advanced, state-of-the-art lever network utilizing Acrison designed and manufactured heavy-duty stainless steel flexures for all pivotal connections
