Rate Controllers

Rate controllers are compact, closed-loop single-feeders for use in a variety purposes. These purposes include auger, belt and vibratory-based feeders, converting them from volumetric to gravimetric. After supplying excitation to the load sensors, the weight is digitalised and the rate controller provides an analogue output to control the feeder speed. The rate controller is often referred to as digital rate controller or loss-in-weight controller. Unlike weighbridges which are used to calculate the weight on trucks with loads on them, rate controllers are used to measure weight as it decreases (or trucks are unloaded) and control it accordingly. They are commonly used in mines and quarries, rubbish dumps / recycling centres, bulk liquid and powder movement, household goods, and electrical equipment.
