Belt weighing

Simple installation and low maintenance

Milltronics belt scales from Siemens combine simple installation, quick calibration and low maintenance (no moving parts) with high repeatability. The result is increased productivity.


With minimum hysteresis and high linearity, lateral forces have no influence on the measuring accuracy and all load cells are protected against overloading. Flexible options are available for high accuracy, light loads or high load-bearing capacity as well as installation in hazardous areas.


Continuous in-line weighing and feeding

A weighfeeder system is an engineered-to-order conveyor integrated with a belt weigh bridge and speed sensor. A variable speed drive allows for the flow of material to be controlled by a given set-point chosen in the BW500 integrator or with a PLC through SIWAREX electronics. This allows the weighfeeder to provide precise weighing accuracies, and to improve blend consistencies, accountability and record keeping.


Siemens weighfeeders are virtually maintenance-free to ensure unmatched performance, making them indispensable for automated production processes that require continuous in-line weighing and feeding. All versions are also available with a corrugated edge belt. The height of the flange as well as the size and width of the belt can be custom-tailored according to the requirements of the application.

Solids flow meters

SITRANS heavy-duty, low-maintenance dry solids flowmeters provide continuous in-line weighing of dry bulk solids, free-flowing powders and granular material.

All models produce accurate, repeatable results and may be used for critical functions such as batch load-out and blending. Safe overload protection is a standard feature. Constructed of painted mild steel, SITRANS solids flowmeters are totally enclosed and dust-tight. Stainless steel and hazardous area versions are also available.

Loss-in-weight scale

Continuous dosing applications

A loss-in-weight system can help you to achieve the needed level of accuracy in continuous dosing applications. With SIWAREX FTC weighing modules, you can set up and integrate the loss-in-weight system easily. The auto-setup functionality helps in the commissioning of the scale. The electronics determine the most important settings like output, PID and stability parameter. SIWAREX FTC steadily optimizes these settings during processing.


Operators can use standard SIMATIC HMI components from Siemens for all operation, calibration and fault diagnostic functions of the scale. Siemens systems are scalable from single to multi-component dosing to applications.
