What factors should be considered when choosing an electronic belt scale?

Many people have a misconception about selecting electronic belt scales, focusing solely on factors like accuracy and price. Among the numerous customers who consult Guonuo, many start by asking questions like "What's the price for a scale with 0.5% accuracy?", "Can your belt scale achieve 0.2% accuracy? How much does it cost?", or "Are there specific parameters for pricing an electronic belt scale? Is there no universal model? What's the price for a universal one?" Some even inquire about prices without understanding the actual parameters of their usage needs.

In fact, electronic belt scales differ from other products due to their wide range of applications, varying scenarios, and complex on-site environments. To adapt to these environments, there is no such thing as a "universal" electronic belt scale. The price of an electronic belt scale is not solely determined by its accuracy; it also depends on various practical parameters of on-site usage. Accuracy is just one aspect.

1. Material

   Electronic belt scales are metering devices for continuous weighing of bulk materials. However, not all materials are suitable, such as highly viscous or high-moisture materials, which can stick to the belt, causing repeated measurements and inaccurate results. Before choosing an electronic belt scale, confirm whether the material characteristics are suitable.

2. Belt Width

   Electronic belt scales are installed on belt conveyors and must match the conveyor's belt width to be used. This is one of the basic conditions for selecting a belt scale. When choosing, inform professionals of this parameter to help them make accurate judgments and formulate precise plans.

3. Belt Speed

   Different types of belt speed sensors are suitable for different belt speeds, and belt speed significantly affects the accuracy of electronic belt scales. For the same scale, a decrease in belt speed improves accuracy. Therefore, belt speed is also an important factor to consider when selecting a scale.

4. Operating Environment

   Electronic belt scales are typically used in industrial settings with complex environments. Different environments require different scale performances. For example, in mines, explosion-proof electronic belt scales with explosion-proof qualifications are required; in environments with corrosive substances, special materials and corrosion-resistant treatments are needed. Thus, the operating environment also impacts accuracy and price and should be considered.

5. Weighing Range

   Electronic belt scale sensors have a range. Choose a sensor that matches the material throughput to avoid overload damage or insufficient range for the desired weighing effect. When selecting a belt scale, consider the hourly throughput and choose a corresponding sensor range.

6. Inclination Angle of the Conveyor

   Different electronic belt scales can adapt to different conveyor inclination angles, which directly relate to measurement accuracy. For example, Guonuo Technology's FSD high-precision electronic belt scale can adapt to inclination angles up to 30 degrees. For smaller angles, choose an overall suspended scale frame structure; for larger angles with less stringent accuracy requirements, select a lever structure.

7. Length of the Conveyor Frame

   Electronic belt scales have a range. If the conveyor length is insufficient for scale installation, measurement cannot be performed, and conveyor length extension may be needed. Additionally, the number and type of belt scales vary for different conveyor lengths, which should also be considered when selecting a scale.

8. Measurement Accuracy

   As a metering instrument, measurement accuracy is always a key focus for customers. Naturally, higher accuracy comes with a higher price. Choose measurement accuracy based on actual needs, avoiding unnecessary cost increases by blindly pursuing high accuracy.

When selecting an electronic belt scale, customers should not solely focus on accuracy and price. Accuracy is not the only factor determining the price. To ensure the scale meets actual needs and is stable in the on-site environment, various factors should be comprehensively considered. Customers should provide as detailed demand parameters as possible to professionals when choosing a belt scale.

For electronic belt scale manufacturers, giving prices without thoroughly understanding customer needs is highly unprofessional. Guonuo Technology has professional engineers who meticulously understand customer needs, even conducting on-site inspections, to formulate detailed and accurate plans and quotes.
