A Qualified Electronic Belt Scale Must Pass These Tests Before Leaving the Factory

In industrial production, electronic belt scales are widely used and highly important automated measurement devices for continuously monitoring and controlling material flow, while providing users with production measurement data.

To ensure long-term stable, precise, and reliable operation of electronic belt scales, they must undergo a series of rigorous performance tests and verifications before leaving the factory. A qualified electronic belt scale must pass strict testing and inspection before delivery, and a qualified belt scale manufacturer must complete product testing to a higher standard.

Guonuo Technology has always adhered to the principle of prioritizing product quality. The electronic belt scales it manufactures must undergo a series of rigorous tests and inspections before leaving the factory, including routine inspections of both hardware and software aspects of the belt scale, as well as customized inspections for clients.

Inspection items for Guonuo Technology's electronic belt scales include:

1. Product Appearance Inspection

   Observe the external appearance of the scale body, instrument, and related components of the electronic belt scale. No visible craftsmanship issues should be present.

2. Hardware Testing

   Hardware testing is the first step in belt scale testing, primarily including functional testing, hardware performance testing, safety testing, and environmental adaptability testing. Functional testing ensures that all functional modules of the belt scale operate normally, such as the weighing sensor accurately measuring material weight. Hardware performance testing mainly includes testing the sensitivity of the weighing sensor. Safety testing ensures the safety performance of the belt scale under abnormal conditions. Environmental adaptability testing simulates performance in actual application scenarios.

3. Software Functionality

   Guonuo's belt scale software functionality testing includes completeness testing and performance testing. Completeness testing verifies that all functional modules operate normally and that interfaces are stable and reliable. Performance testing examines the response speed, data processing capability, real-time data display, and accuracy of the belt scale software.

4. Accuracy Calibration

   An essential step before leaving the factory is accuracy calibration for Guonuo's belt scales, including accuracy testing, error analysis, and accuracy stability testing. Accuracy testing ensures that the actual measured values of the electronic belt scale are within the allowable error range of the standard values, meeting the client's required accuracy. Error analysis identifies the causes of errors, determines factors affecting accuracy, and resolves them. Accuracy stability testing assesses the belt scale's accuracy performance over extended operation.

5. Reliability Assessment

   Before leaving the factory, Guonuo tests and evaluates the mean time between failures (MTBF) and mean time to repair (MTTR) of the electronic belt scale to ensure continuous and stable operation after deployment.

6. Environmental Adaptability Performance Testing

   Guonuo's electronic belt scales undergo simulated various actual application scenarios before leaving the factory to test their performance, known as environmental adaptability performance testing. For example, testing operation under high and low-temperature conditions, and conducting explosion-proof performance testing for explosion-proof electronic belt scales.

7. Unconventional Testing

   Electronic belt scales have customized characteristics, as application conveyors and process environments vary, leading to different scale frame sizes. Before leaving the factory, in addition to routine testing, Guonuo Technology conducts strict testing on customized dimensions and software functionalities for clients.

In addition to rigorous and comprehensive testing, Guonuo Technology also records testing procedures and results, establishes strict inspection processes and systems, and enforces them strictly to ensure that products leaving the factory are qualified and can operate accurately, reliably, safely, and stably at client sites.
