Weighing errors and future development trends

Measurement error control countermeasures

In practice, the reason why the scale measurement error, in addition to the impact of its own quality, and personnel operation, technical level, etc. have a direct correlation. First of all, the comprehensive quality of the checking personnel affects the accuracy of the scale checking, in the checking operation if the personnel did not operate in accordance with the standard procedures for metrological checking, it is easy to lead to the measurement of the scale checking error. For example, when checking the push and balance performance of scales, it is very easy for the checkers to neglect the variability checking of empty scales. Secondly, scales are mainly used for measuring the weight of objects, and based on the functional level, they can be divided into electrical controls, load cells, weighing display controllers, etc. With the development of social science and technology, scales are mainly used for measuring the weight of objects. With the development of social science and technology, the scale function system has undergone great changes, and has been developed from the traditional measurement to modularization and intelligence, but because the control technology needs to be improved, there are still large deviations in the measurement rate, standard range, and so on.

For the measurement of electronic scales, usually used in trade markets and other fields, which includes six weighing points such as 5 g, 10 g, 20 g, corresponding to the permissible error of ± 0.1 g, ± 0.5 g, etc., so when carrying out the measurement and calibration of electronic scales, the calibration personnel should attach great importance to the measurement point and the permissible error value, and detailed records of the standard weight data during the weighing period, which can be measured by the measurement error of the electronic scales can be controlled within reasonable limits. This can control the measurement error of electronic scales within a reasonable range. At the same time, the certifying officer should also fill in the “Certificate of Certification” reasonably with the situation of the electronic scale, and submit the certificate to the competent department for examination, which can also improve the measurement effect of the electronic scale. Meanwhile, in the process of repetitive calibration, in order to improve the accuracy of the calibration results, the calibration personnel need to put the electronic scale measuring tools in different conditions for calibration, and then do a good job of recording the calibration data, which can also improve the accuracy of the calibration results.

Measurement of the future development trend of the weighing industry

Measurement scales will be transformed from analog electronic scales into digital electronic scales, along with the development of microelectronics technology, digital sensors manufacturing process is more and more perfect, analog electronic scales will be effectively replaced by digital electronic scales, digital electronic scales due to the reliability of strong, good measurement results, so it will be recognized by the market. The non-automatic scales will also continue to develop towards automatic scales, and traditional, single scales will be replaced by automated equipment, weighing systems. With the development of the measuring scale industry, China’s use of measuring scales is no longer a single function, and integrated into the management, control and monitoring, etc., the manufacturing enterprises will also undertake the manufacture of transmission and storage equipment. As for the weighing technology will change from the traditional static weighing to dynamic weighing. Measurement from the analog measurement span to digital measurement, single-parameter measurement will become multi-parameter measurement, and the technical performance of the scale will also be towards the direction of strong stability, high accuracy and good rate of development. In addition, measuring scales will tend to miniaturization, modularity, integration and intelligent direction. With the application of measuring scales, upgrading, weighing equipment will continue to reduce the size, height will be reduced, but also show a split combination of modular trend. Under this trend, the reliability and versatility of the products will be greatly improved, and the production quality and effect of the scale products will be strengthened.
