 Ramsey Loss-In-Weight and Volumetric Feeders accurately control the flow of powders, pellets, flakes or granules to critical processes. They handle hot, floodable and difficult material and are unaffected by dust
and material accumulation. These feeders can increase your profits by maintaining quality and weighing accuracy, reducing material waste, and improving blend consistency.
Theory of Operation
The accurate feeding of dry bulk material is often critical to maintaining product quality. A feeder that weighs accurately and reliably can reduce material waste, improve blend consistency and increase profits.
Ramsey Loss-In-Weight Continuous or Batch Feeding Systems from Thermo measure the mass flow rate and total mass of various bulk materials, such as powders, pellets, flakes and granules. We incorporate the standard, low capacity and sanitary versions of our volumetric feeders into a complete gravimetric feeding system, providing accuracies of ±0.25% to 1.00% and more reliable
process control over typical volumetric feeding systems.
There are many advantages to utilizing loss-in-weight feeders. They can handle hot, floodable and difficult materials; are unaffected by dust and material accumulation; and are well suited for low feed rate applications. The entire feeding system is weighed, so there are no errors caused by belt tensioning or tracking. No transportation lag time exists, ensuring precision second-to-second
accuracy. Feed accuracy can always be checked during normal operation without the need for sampling.
The Ramsey Micro-Tech 2104 Loss-In-Weight Feeder Controller is specifically designed for continuous or batch loss-in-weight or gain-in-weight applications. It's easy to operate and calibrate with the aid of large easy-to-read displays; straightforward, tactile-touch keyboards; and software that prompts you through proper set-up and operational procedures. A single Ramsey Micro-Tech
2104 is capable of operating two independent loss-in-weight systems, which ultimately contributes to cost savings. A UL-approved version is also available.
