What factors are related to the accuracy of weighing sensors? 2025-08-28 What factors are related to the accuracy of weighing sensors? In industrial production, weighing sensors are widely used to measure the weight of objects. However, the accuracy of the weighing sensor is an important factor in evaluating its performance. Accuracy refers to the difference between the sensor output value and the measured value, and is based on factors such as sensor reliability and stability. Therefore, this article will explore the accuracy of weighing sensors and their applications. What is the accuracy of a weighing sensor The accuracy of a sensor refers to the difference between its output signal and the measured value, usually expressed as a percentage, known as accuracy indication error. Accuracy indication error is divided into quantitative, percentage, and numerical indication errors. In weighing sensors, quantitative error (direct or direct error) refers to errors caused by factors such as hardware structure, material parameters, manufacturing processes, etc; Percentage error (or relative error) refers to the error in the ratio between the sensor output and the true value; Digital error refers to the accuracy error generated by digital calculations (such as AD converters). Factors affecting the accuracy of weighing sensors Mechanical misalignment: Mechanical misalignment is a common cause of decreased sensor accuracy during sensor operation. The causes of mechanical misalignment include physical deformation, structural corrosion, and failure to install standards. Signal processing error: Signal noise levels that are too high or too low can affect the output of the sensor. The causes of such errors include small design scale, loss or poor quality of signal processing circuits, etc. Environmental factors: Weighing sensors are applied in different environmental conditions, and different environmental conditions will have an impact on the performance of weighing sensors. Such as temperature changes, working life, usage environment, etc. Improvement of Accuracy of Weighing Sensors Choosing the appropriate sensor: Firstly, the appropriate weighing sensor model should be selected based on the actual application scenario to obtain more accurate weight measurement results. Carefully select the application environment: When installing and applying weighing sensors, attention should be paid to various environmental factors such as temperature and mechanical wear, which can affect the accuracy of the weighing sensor. Some standardized and reasonable usage ranges should be followed, such as avoiding environments with too high or too low temperatures. Instrument calibration: Proper calibration can effectively improve the accuracy of weighing sensors. Calibration ensures the response characteristics, sensitivity, and stability of sensors. Laboratory calibration is to provide accurate measurement results of weighing sensor accuracy and improve the reliability of weighing sensor calibration. Conclusion The accuracy of a weighing sensor is a significant parameter for measuring the accuracy of its device. A series of measures such as enhancing the stability of instruments, reducing equipment vibration, and improving environmental conditions can all improve the accuracy of weighing sensors. Calibration and other operations can also ensure the continuous and accurate operation of the weighing sensor.

What industries are weighing sensors mainly used in? 2025-08-28 What industries are weighing sensors mainly used in? Electronic Weighing Scheme The electronic weighing solution is suitable for: electronic scale platform scales, weighing scales, belt scales, forklift scales, floor scales, truck scales, track scales, livestock scales, etc. Weighing solution for material tanks Enterprises extensively use various storage tanks and measuring tanks in material storage and production processes. There will be issues with measuring materials and controlling the production process. The application of weighing sensors can effectively solve this problem. Production process control plan The widespread application of weighing sensor products in production process control systems is suitable for automated weighing control systems in canning weighing systems, ingredient weighing systems, and weight inspection and sorting systems Unmanned retail weighing solution This solution involves installing weighing sensors on each aisle of unmanned retail cabinets to determine the items taken by consumers by sensing changes in the weight of goods on the aisle or changes in the quantity of identical products of the same weight per unit.

Intelligent weighing equipment, a tool to improve production efficiency 2025-08-28 Intelligent weighing equipment, a tool to improve production efficiency Weighing equipment refers to weighing instruments used for industrial weighing or trade weighing. Due to its wide application range and different structures, there are various types of weighing devices available. According to different classification standards, weighing equipment can be classified into multiple types. Classified by structure: 1. Mechanical scale: The mechanical scale mainly adopts the principle of leverage.it, which is completely mechanical and requires manual assistance, but does not require electricity or other energy. The mechanical scale is mainly composed of levers, supports, connectors, weighing heads, etc. 2. Electromechanical scale: Electromechanical scale is a type of scale between mechanical scale and electronic scale. It is an electronic conversion based on a mechanical scale. 3. Electronic scale: The reason why electronic scales can weigh is because they use weighing sensors. The weighing sensor converts signals, such as the pressure of the object being measured, to obtain its weight. Classified by purpose: According to the purpose of weighing equipment, it can be divided into industrial weighing equipment, commercial weighing equipment, and special weighing equipment. Such as industrial belt scales and commercial platform scales. Classified by function: Weighing equipment is used for weighing, but different information can be obtained based on the weight of the object being weighed. Therefore, weighing equipment can be divided into counting scales, pricing scales, and weighing scales according to different functions. Classified by accuracy: The principles, structures, and components used in weighing equipment vary, resulting in different accuracies. Currently, weighing equipment is roughly divided into four categories based on accuracy: Level I, Level II, Level III, and Level IV. With the continuous development of weighing technology, weighing equipment is moving towards intelligence, higher accuracy, and faster speed. Among them, computer combination scales, ingredient scales, packaging scales, belt scales, weighing scales, etc. can not only meet the high-precision and high-speed weighing of various products, but also be customized according to the specific needs of customers. For example, a batching scale is a measuring device used for customers to quantitatively mix various materials, a packaging scale is a measuring device used for batch material quantitative packaging, and a belt scale is a product that measures materials based on the conveyor. The computer combination scale can not only weigh various materials, but also count and measure them. It has a wide range of applications and has become a powerful tool for many manufacturing enterprises to improve production efficiency and enhance economic benefits. There are not many food companies in China that use combination scales for quantitative weighing. One reason is that some domestic food factories do not know about combination scales. The other is mainly limited by the high price of imported combination scales, which makes it impossible to experience the high efficiency brought by the world's most advanced weighing equipment. More domestic enterprises pursuing high-speed and efficient development will be able to use intelligent combination scales, eliminating outdated methods of cup containing or fully manual quantitative weighing and packaging, and equipping themselves with high-tech and more automated combination weighing and packaging systems, thus initiating an improvement and enhancement of the production environment, increasing the degree of automation in production and management, reducing costs, creating a new revolution in civilized production, and continuously improving economic benefits for enterprises. The intelligent weighing system can be widely applied in industries such as food manufacturing, pharmaceutical industry, refined tea processing, seed industry, etc. At the same time, it has also been expanded to a greater extent in the fields of traditional Chinese medicine, feed, chemical industry, and hardware.
