Belt scale SITRANS WB310


SITRANS WB310 is a heavy-duty, full-frame two load cell, pivoted pan based, belt scale used for process monitoring.

SITRANS WB310 belt scale provides continuous in-line weighing on a variety of products in recycling industries. It is proven in a wide range of tough applications from sorting (in-coming processes) to production monitoring.

SITRANS WB310 uses parallelogram-style load cells that result 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.

Operating with Milltronics BW500, SIWAREX WP241, or FTC microprocessor- based integrators, WB310 provides indication of flow rate, totalized weight, belt load, and belt speed of bulk solid materials. A speed sensor monitors conveyor belt speed for input to the integrator.

SITRANS WB310 is installed in a simple drop-in operation and has a complete full length frame to ensure support during operation. With minimal rotating parts, maintenance is kept simple and easy, with just periodic calibration checks and greasing of bearings required.
