Manufacturer's Summary: Common Causes and Solutions for Inaccurate Measurement by Electronic Belt Scales

Electronic belt scales are devices used for weighing materials on conveyor belts. Due to their characteristics of high precision, high automation, high weighing efficiency, and provision of weighing data to users, they are widely applied in the transportation of bulk materials in industries such as coal, cement, and building materials.

However, during use, issues such as inaccurate measurement results and significant fluctuations in measurement values may arise, posing problems for production and quality management. Guonuo Technology, a manufacturer of electronic belt scales, summarizes and introduces several common causes of inaccurate measurement by electronic belt scales and their solutions based on user feedback, pre-sales and post-sales on-site situations, as well as extensive dynamic weighing theory.

1.  Improper Calibration 

   Electronic belt scales generally undergo calibration before leaving the factory. However, various factors during long-distance transportation, installation, debugging, and use, such as loosening of mechanical parts and sensor aging, may lead to inaccurate resetting of the electronic belt scale, thereby affecting measurement accuracy.

Calibration should be performed according to the manufacturer's provided operating procedures. Improper or incorrect manual adjustments can also result in inaccurate and unstable weighing measurements.

Solution : Regularly inspect and maintain the electronic belt scale, and perform calibration based on actual conditions. Naturally, the more frequent the calibration, the more accurate the measurement will be.

During calibration, ensure that all devices related to the electronic belt scale are turned off, verify accuracy under no-load conditions, and make detailed equipment adjustments according to various operating conditions to ensure equipment precision and reliability.

2.  Interference with Electronic Belt Scales 

   During use, electronic belt scales may be subject to interference from various factors, such as electromagnetic interference, gravitational changes, and magnetic field interference, all of which can lead to deviations in measurement results.

    Solution : When corresponding faults occur in electronic belt scales, consider implementing shielding measures or using special isolated brackets to reduce the likelihood of interference. Additionally, strictly control the surrounding environment during use to avoid strong vibrations and external electromagnetic radiation, thereby minimizing the impact of interference on the electronic belt scale.

3.  Mechanical Issues 

   The mechanical components of an electronic belt scale (such as the conveyor belt) can also affect measurement accuracy. The tension of the conveyor belt may change over time and with different transported materials, thereby influencing measurement results.

    Solution : Regularly inspect parameters such as the tension, speed, and conveying direction of the conveyor belt. Promptly adjust and maintain any identified issues, such as replacing worn conveyor belts or unusable drive rollers, or coordinating the replacement of new equipment to ensure standards such as symmetry.

4.  Equipment Damage 

   After prolonged use, various components of the electronic belt scale may experience aging or wear. Problems such as the control panel's connecting wires reaching their lifespan limit and the sensor's rocker arm becoming loose can all lead to inaccurate measurements.

    Solution : When faults are identified in the electronic belt scale, the first step is to inspect and repair them promptly, replace damaged parts, and implement detailed inspection measures to prevent similar issues from recurring. This differs from adhering to investment operation management.

Electronic belt scales are crucial measuring devices in coal production, and their accuracy and stability are closely related to equipment operational efficiency. Common causes of inaccurate measurement include improper calibration, interference, mechanical issues, and equipment damage. To resolve inaccurate measurement problems, it is essential to first understand a series of causes and then perform maintenance, inspections, and logistical support accordingly. Improving daily management practices is an important condition for ensuring the normal operation of the equipment.
