The 1200/3600 Series of high-capacity weigh feeders from Siemens Energy & Automation Inc. are designed to provide solid performance in rugged operating environments. The weigh bridge has a patented dual-idler, stainless-steel, torque shaft suspension with no moving parts designed to eliminate material build-up. This design reduces dead load and applies live load to the load cells. The load cell is completely encapsulated and hermetically sealed to guard against contamination from dust, moisture or corrosion. The result is reliable accuracy and low maintenance, the company says.
