Belt scale SITRANS WB300


SITRANS WB300 is a heavy-duty, full-frame four load cell belt scale used for process and load-out control. Rails not included with belt scale.

SITRANS WB300 belt scale provides continuous in-line weighing on a variety of products in primary and secondary industries. It is proven in a wide range of tough applications from clinker (in cement production), to mining, iron, and steel.

The WB300’s proven use of shear beam style load cells results in fast reaction to vertical forces, ensuring instant response to product loading. This enables it to provide optimum accuracy and repeatability even with uneven loading and fast pan speeds.

Operating with Milltronics BW500, SIWAREX WP241 or SIWAREX FTC micro-processor-based integrators, the WB300 provides indication of flow rate, totalized weight, belt load, and belt speed of bulk solid materials. A speed sensor monitors conveyor pan speed for input to the integrator.

The WB300 is installed in a simple drop-in assembly and has a complete full length frame to ensure support during operation. Existing rails are then attached to the mounting points. Maintenance is kept to a minimum, with just periodic calibration checks required.
