Belt Scale

A Belt Scale System is a specialized weighing solution used in various industries to measure the flow rate and total quantity of materials transported on a conveyor belt. It is particularly important in industries where accurate measurement of material movement is critical for production, inventory management, quality control, and regulatory compliance. The system consists of several components that work together to provide accurate and reliable weight measurements.

Industries that commonly use Belt Scale Systems:

  • Mining and Quarrying
  • Agriculture and Farming
  • Construction
  • Recycling and Waste Management
  • Bulk Material Handling
  • Food and Beverage
  • Pharmaceuticals
  • Energy and Utilities

Key components of a Belt Scale System:

  1. Load Cell or Weighing Sensor: This is the primary component responsible for measuring the weight of the material on the conveyor belt. Load cells are installed at strategic points within the weigh frame along the conveyor to measure the force exerted by the material. The measured force is then converted into weight using appropriate calibration factors.

  2. Weigh Frame: A weigh frame, also known as a weigh bridge or weighing frame, is an essential component of various weighing systems used to measure the weight of objects, vehicles, or materials. It serves as the foundation upon which the load is placed, and it contains the necessary sensors and mechanisms to accurately measure the weight. The design and construction of a weigh frame are crucial for ensuring accurate and reliable weight measurements.

  3. Controller/Indicator: This component receives signals from the load cells and other sensors, processes the data, and calculates the weight and flow rate of the material. It typically includes a digital display or interface that allows operators to monitor and control the system.
  4. Speed Sensor: To calculate the flow rate accurately, the system requires information about the conveyor belt’s speed. Speed sensors, such as encoders or tachometers, measure the belt’s velocity and provide input to the controller. Available heavy duty speed sensor with protection rating up to IP68.
  5. Data Communication:  Offer data communication capabilities, allowing integration with PLCs, supervisory control and data acquisition (SCADA) systems or other software platforms. This enables real-time monitoring, data analysis, and reporting.
