The Master™ 421 Belt Scale Weigh Frame is an excellent choice for flat belt conveyors handling light-capacity materials. Designed to meet the demands of food production and granular material processing, the 421 delivers reliable weight measurements where precision is key but belt load and speed are moderate.
Its open-frame structure ensures easy access for cleaning and maintenance, making it especially suitable for applications requiring sanitary conditions. The roller is supported on both ends by hermetically sealed load cells and mounted externally to ensure long-lasting performance. With two BM11 bending beams providing load detection, the 421 offers a stable and accurate weighing solution even in challenging environments.
Custom-built for operational efficiency, the 421 weigh frame is also available in configurations suited for hazardous or explosive areas, giving it wide industrial appeal.
