Applications
The belt scale can provide continuous online measurement for various materials in different industries.The belt scales are widely used in various harsh environments in mines, quarries, energy, steel, food processing and chemical industries, fully proving the excellent quality of belt scales. The belt scale is suitable for different materials such as sand, flour, coal or sugar.
The belt scale uses the parallelogram load cell developed by our company, which responds quickly to the vertical force and ensures the sensor's rapid response to the material load. This enables belt scales to achieve high accuracy and repeatability even with uneven material and fast belt movements. It can provide instantaneous flow, cumulative quantity, belt load, and belt speed display. The speed sensor is used to measure the conveyor belt speed signal and send it to the integrator.
The belt scale is easy to install, remove the existing set of rollers of the belt conveyor, install it on the belt scale, and fix the belt scale on the belt conveyor with four bolts. Because there are no moving parts, the Belt Scale is low maintenance requiring only periodic calibration.

1. Accuracy description: On the installed belt measuring system approved by the manufacturer, the cumulative amount measured by the belt scale is compared with the weight of the tested material, and the error is less than the above standard. The amount of test material must be within the design range, and the flow rate must be stable. The minimum amount of material must be the higher of three full revolutions of the belt or 10 minutes.
2. If the belt speed is higher than the value described in the manual, please consult the engineer.
3. Engineer inspection is required.
