A suspended hopper (or hanging scale hopper) is a type of weighing system commonly used in batching, blending, and dispensing operations where materials are weighed before being discharged. Unlike platform scales where the hopper rests on the load cells, a suspended hopper is hung from above using rods or cables, with the load cells installed in tension between the fixed support structure and the hopper’s suspension points. This configuration is particularly effective for systems requiring high accuracy, especially in dusty or wet environments, because it allows the load cells to be positioned away from the direct material flow and facilitates easier cleaning underneath the hopper. The material is fed into the top, weighed, and then discharged through a gate at the bottom. The total weight measured includes the tare weight of the hopper and the gross weight of the material. The most commonly used type is the S-Beam Load Cell (or S-Type) because its design is inherently suitable for sensing tension forces (the weight of the suspended hopper pulling down). Typically, three or four S-Beam load cells are connected to the hopper, ensuring the weight is distributed and measured accurately, compensating for eccentric loading. An Electronic Weighing Controller/Indicator is used to process the millivolt signals from the multiple load cells. This device sums the signals, converts the total into a stable weight reading, applies the necessary calibration and tare subtraction (to account for the hopper’s weight), and provides control outputs (often via a PLC) for automated functions like starting and stopping the feed system based on the target batch weight.
