Their superior performance and stability not only improve the efficiency of material settlements for industrial and mining enterprises but also deeply integrate into production monitoring and comprehensive data management for the enterprise, meeting modern weighing requirements.
A weighbridge is a commonly used measuring device, widely applied across various industries. Accuracy has increasingly become a challenging issue for weighing instruments. This article introduces several factors that affect the accuracy of weighbridges.
1. Principle Analysis
A weighbridge typically consists of a weighing display meter, weight sensors, the mechanical structure of the weighing platform, a computer, a printer, and other components. Place the item to be weighed or a loaded truck on the platform, which then transmits the weight to the load-bearing head. This causes the elastic body of the weight sensor to deform, and the strain gauge bridge on the elastic body loses balance, outputting an electrical signal proportional to the weight. The signal is amplified through a linear amplifier and then converted to a digital signal via an A/D converter. The weight signal is processed by the meter's microprocessor (CPU) and the weight data is displayed. With a printer configured, weight data can be printed for record-keeping. If a computer is connected, the measurement data can be input into the computer management system for comprehensive management.

Generally, it is necessary to check the weight limit device of the ground scale every three quarters to ensure it is intact and not stuck. In case of abnormalities, a timely report is required. 3. Inspection of the clearance and connection of the unloading bolts (every six months) - These areas often accumulate small debris, which over time can affect the daily maintenance of the ground scale, so they need to be checked and cleaned every six months. 4. Sealing and connection check of the junction box (annually) - As a core electronic component of the ground scale, the junction box requires waterproofing and moisture resistance.

Several Factors Affecting Accurate Weighing
After understanding the principle of weighbridges, analyze the impact on the accurate weighing of car scales from several aspects: the sensor support beam, the installation of the sensor, and the installation foundation.
2.1 Sensor Support Beam
In the manufacturing of the weighing platform, the production of the sensor support beams is particularly crucial. The flatness and positional accuracy of each support beam must be maintained within a certain allowable range. Otherwise, it will directly affect the installation and accuracy of the sensor, ultimately impacting the accuracy of the automotive scale. When welding the support beams, first adjust the position of the support beam using tools, ensuring the flatness and positional accuracy are <3mm. Then, spot weld, with at least 6 welding points on each end. After that, use full welding for the rest.

2.2 Installation and Usage of Sensors
The strain gauge weight sensor itself is a robust, durable, and reliable electromechanical product; however, it still requires proper installation and use. Installation: Correct installation of the sensor is crucial for ensuring the accuracy of the weighing instrument; otherwise, it may cause measurement errors and even damage. Handle the weight sensor gently; the installation support beam surface should be flat and clean, free of any oil stains. The support beam must have sufficient strength and rigidity. Try to adjust the installation base to the same level, with a level error <3mm, and align the sensor's center axis with the support beam's center. Secure it in two steps: once for pre-tension and once to reach the required force, ensuring that the torque does not exceed the limit during tightening.
When selecting sensors, it is recommended to choose sensors with the same sensitivity, either all positive or all negative, within the same weighing body to ensure accuracy. Good limitation is essential: proper limitation in both the longitudinal and lateral directions of the weighing body is crucial. The sensor should be loaded correctly, and efforts should be made to avoid lateral forces, additional bending moments, and torques, as these can affect the weighing results. The principle requires that the longitudinal gap between the ram and the plate be 3mm to 4mm at each end, and the lateral gap be 1.5mm to 2mm at each end.

In the 1980s, we developed and produced electronic price scales, weighing controllers, and high-performance weighing sensors. At the end of the 1970s and the beginning of the 1980s, during the national cleanup and rectification of trademarks, Shanghai weighing factory simplified the trademark by changing the Pingpai brand and removing the balance from the design, then re-registering it. 3. Physical, moving forward.

The rated load of the selected weighing sensor is not the larger, the better; in principle, it should be
Weighing body's high capacity %26lt; rated load of sensor X number of sensors X (0.6-0.7) - weighing body's own weight
3. The Impact of Foundation Installation on Accurate Weighing
The diagonal dimensions of the excavation pit: Controlling the diagonal dimensions ensures that the shape of the excavation pit remains rectangular rather than a parallelogram. If the pit is a parallelogram, it is difficult to position the weighing body properly. Even if it is勉强 positioned, it is prone to "rubbing" and "leaning" phenomena, which naturally affects the accuracy of the weight measurement. The flatness of the weighing platform should be less than 1mm, and the parallelism between weighing platforms should be less than 3mm. If these dimensions are not controlled properly, it can result in significant unbalanced forces and uneven distribution of forces across the weighing sensors, leading to bias errors in the truck scale. Due to the non-linear input signals of the weighing sensors, it is often difficult to achieve consistency during calibration, thereby increasing weighing errors.
