Description
Technical Field
The application relates to the technical field of electronic balances, in particular to an electronic balance for gold weighing.
Background
Gold is a valuable item and therefore requires very high precision in weighing, but it is still unavoidable that weighing errors occur, which are mainly expressed as the degree to which the weighing value deviates from the actual value, usually expressed in percentages or milligrams, and the weighing error of gold is usually required to be limited to within 0.01%, i.e. in 100 grams of gold jewelry, the error must not exceed 0.01 grams.
The main causes of errors in weighing gold include the following:
1. The accuracy of the weighing equipment is affected, the higher the accuracy of the weighing equipment is, the smaller the error is, for example, the accuracy of a common electronic scale is higher than that of a mechanical scale, and the weighing equipment with higher accuracy can meet the gold weighing requirement;
2. Environmental factors such as temperature, humidity, air flow rate, etc. can change the density of the material or the sensitivity of the weighing device, resulting in errors;
3. the level of technology of the weigh-cles varies from one weigh-clet to another, and may vary in terms of method of operation, accuracy of readings, etc., resulting in errors.
4. The characteristics of gold itself, different types of gold, may have differences in weight and density, while gold with smaller components is more susceptible to weighing errors.
Aiming at the related technology, weighing equipment with higher precision and better quality is generally selected when gold weighing is carried out at present; the environment stability of the measuring equipment is ensured in the weighing process, and the influence of factors such as temperature, humidity, air flow rate and the like on the weighing result is avoided; the operation skills and the reading accuracy of the weighing staff are trained, the operation standard is ensured, and the human error is reduced; for gold with a smaller component, the method of taking the average of multiple weighings can be adopted to reduce the error as much as possible.
However, the method further reduces errors, and the requirements on the experience and the proficiency of the weighing staff are unavoidable, so that even if the same gold ornaments are weighed by the same equipment, the errors can be different; the more precise the existing weighing equipment is, the more the existing weighing equipment is disturbed by air disturbance, and meanwhile the weighing efficiency is reduced. Therefore, how to reduce the influence of external factors on the weighing result while ensuring high weighing precision is a problem to be solved at present.
