A belt scale system is made up of three primary components that work together to ensure accurate measurement of material flow:

1. Weigh Frame

The weigh frame is the central part of the system, containing load cells that measure the weight of the material as it moves along the conveyor belt. The frame can either have a roller design, where the belt moves over rollers supported by load cells, or an idler design, where the belt passes over idlers that include load cells for weight measurement.

2. Speed Sensor

The speed sensor accurately tracks the velocity of the conveyor belt. This sensor is typically a tachometer attached to the belt pulley shaft or a magnetic sensor that detects metal tags embedded in the belt. The speed data is essential for calculating the material’s flow rate.

3. Integrator

The integrator is the system's processing unit. It receives the weight signals from the load cells and the speed data from the sensor, then calculates the mass flow rate of the material on the belt. The integrator displays the weight data and can range from a simple display unit to more advanced models with additional features such as data logging, control outputs, and communication interfaces for integration with other systems.

Together, these components work in unison to provide accurate, real-time measurement of material flow, improving efficiency and optimizing material handling processes.
