Belt Scale Accuracy
You remember reading that belt scale spec sheet, impressive numbers: “0.25% accuracy.” It helped justify the model and brand of belt scale you chose. But once the system was installed, something didn’t add up. If you’ve had that moment of doubt, you’re not alone.
When selecting a belt scale, what truly matters is the achievable and maintainable accuracy under actual operating conditions. And that can only be determined after fully understanding the specific conveyor application and site conditions.
Many quoted accuracy figures refer to Full Scale Division (FSD) error measured at maximum capacity, not across the full operating range.
So what does this mean?
It means that the brochure-stated accuracy assumes a perfect weighing application and site conditions.
In controlled, laboratory-type conditions, electromechanical scales can achieve intrinsic accuracies of 0.02%, as is the case for the Process Automation range. However, quoting that figure without context can be misleading.
In practice, accuracy is driven by site-specific realities. It requires engineering the system to suit your plant and to maintain its performance over time.
Inaccurate measurements introduce operational risk and undermine Plant Control and Metal Accounting, which may have far-reaching impact in auditing and efficient operations.
At Process Automation, we engineer for what’s real. We start by understanding your site conditions, then design conveyor belt scales that achieve sustained accuracy where it matters most.
We don’t quote theoretical accuracy. We provide you with high-precision and sustainable measurement solutions on your site, under normal plant operating conditions. You can only manage what you accurately measure.
