SITRANS WW310 is designed for industrial applications such as mining, cement, chemical processing, pulp and paper, and other heavy-duty industries.
Field tested and proven in hundreds of applications, it enhances profitability by ensuring accuracy, enhancing blend consistency, reducing downtime, and improving accountability and record keeping. The unique weigh system reduces dead load and applies live load directly to load cells for accurate measurement. The dual load cells are externally mounted for easy access and maintenance.
It is available in a variety of lengths from 1.6 m (63 inch), belt width from 0.5 m (18 inch) to 1.2 m (48 inch), several different inlet configurations and materials of construction. It can be configured to suit various applications.
Supported by Milltronics BW500 or SIWAREX FTC microprocessor-based integrators for easy blending, batching and feed rate control.
SITRANS WW310 is a medium- to high-capacity weighfeeder used for macro ingredient additives.

Approvals |
Note: Weighfeeder as a whole is not approved for hazardous locations, only electrical components. |
1) Accuracy subject to: On factory approved installations, the weighfeedersystem’s totalized weight will be within the specified accuracy when compared to a known weighed material test sample. The test rate must be within the specified range of the design capacity and held constant for the duration of the test. The minimum material test sample must be equivalent to a sample obtained at the test flow rate for three revolutions of the belt or at least ten minutes running time, whichever is greater.
