Conveyor Belt Weigher System
Description
Belt Weigher System – Dynamic Weighing with Precision
A Belt Weigher is an in motion weighing system designed to measure the mass and/or flow rate of materials being transported over a conveyor belt, regardless of its length or width. These Conveyor Belt Scales weigh the material in motion and determine the rate at which it travels over a specific period.
At Newton, our NBS® Series Weight Integrators are employed to monitor the static weight signal from High-Precision Strain Gauge Load Cells installed on a scale idler positioned beneath the conveyor belt. Once the static load is captured, our integrator combines this data with the belt speed—measured using advanced Speed Encoders—to calculate the mass flow rate (kg/hr or ton/hr).
This integration process enables real-time tracking and continuous monitoring of material flow. The integrator displays this information live on its interface, ensuring transparency and operational control for dynamic weighing applications.
NEWTON excels in delivering customized and reliable Conveyor Belt Weighing Systems, offering high accuracy and seamless in-motion weighing solutions across various industries.
To enhance operational efficiency, we also provide Cloud Automation and SMS Alert Facilities through our Weigh Connect® series Remote Monitoring Device enabling remote monitoring and data access of the entire weighing system anytime, anywhere.
At NEWTON, we suggest the following for selecting the best Installation Location for the precise weighing on the conveyor:
- Choose an area with constant Belt tension
Constant belt tension plays a key role. For optimal accuracy of the scale, the tension must remain constant to avoid inaccurate measurements. It is best to install the scale close to the tail section, where tension variations from no load to full load are minimal.
- Belt Scale not to be installed near the materials loading point
The loading point of materials will generally be turbulent and installing a conveyor belt scale near the loading point can lead to poor performance. For accurate measurements, materials on a conveyor belt should not be weighed before they are completely settled.
We suggest determining the distance of belt length between the loading point and the point at which the belt becomes settled for selecting the location of the scale. Installation of the scale around the head pulley or the tail pulley of the conveyor belt can produce the similar problems. Ideally a scale should be installed at least one conveyor idler away from the point where turbulence stops.
- A steep incline and locations where the conveyor forms a convex or concave curve is a poor location choice
When a conveyor belt is at an angle of more the 15 degrees, the chances of material roll back increases greatly. A belt scale installed on a steep incline can be weighing the materials multiple times if material roll back is occurring.
Locations where the conveyor belt forms either a convex or a concave curve make for an inappropriate belt scale installation point. This could give rise to problems such as a belt lifting up from the curve preventing a good empty belt zero balance for the scale.
- Consider vibration & weather
A belt scale is an inherently sensitive device and should be isolated from equipment that can induce harmful or disturbing vibration. Equipment such as crusher, vibratory feeding equipment, bins subject to hammering and hammer mills should be avoided.
Weather conditions with temperatures below -20 degrees C can cause ice and frost build-up on the belt which creates unreliable speed sensing. It is also recommended your conveyor belt scale is in a covered area for outdoor installations.
