Electronic scales and electronic balances are one of the important types of weighing instruments. Both It belongs to the category of non-automatic weighing instruments. They are widely used in social production and life and scientific research fields. With the continuous development of science and technology, electronic scales and the implementation technology and types of electronic balances are also constantly improving and changing. Both are electronic weighing instruments are currently the most widely used. As electronic technology continues to improve,
Today, the application scope of the two is expanding year by year, and they have gradually replaced mechanical weighing instruments.It becomes a matter of time. They collect data through modern sensor technology set, combine electronic technology and microcomputer technology to quickly achieve the target object weighing operations. Compared with traditional mechanical weighing instruments, it is simple and easy to use.It is easy to operate and has fast weighing speed. With the support of modern information technology, it can achieve a higher level of automation and intelligent operations, greatly improving work efficiency rate. After years of development, electronic scales and electronic balances have developed many each type forms a relatively rich and three-dimensional category system, suitable for multiple fields.Weighing operations in the field. Lifting electronic scales can be divided into different categories according to different functions.For electronic counting scales, electronic pricing scales, electronic weighing scales, electronic truck scales, electronic sub-table scales, electronic floor scales, etc. Electronic balances can be divided according to their accuracy .For ultra-micro electronic balance, micro balance, semi-micro balance, constant electronic balance.Balances, analytical balances, precision electronic balances and many other types.The connection between the two: Electronic scales and electronic balances are both non-automatic weighing instruments.Both work on the same principle. Therefore, the testing methods are basically the same.Although domestic calibration regulations for these two types of weighing instruments are different, European and American
For these two types of weighing instruments, the country’s testing methods are reference R76 non-automatic
Weighing Instruments International Recommendations.
The difference between the two: Since there are two names, there must be a difference between the two.
Yes, there is still a big difference between electronic scales and electronic balances.
(1) Electronic balances focus on high precision and small weighing capacity. And the electronic scale side
The important thing is low precision and large weighing capacity. Although the accuracy level of electronic balances is
For ○Ⅰ, ○Ⅱ, ○Ⅲ, ○Ⅳ. However, the currently commonly used electronic balances are still based on
○Ⅰ, ○Ⅱ mainly. Electronic scales are only divided into ○Ⅲ and ○Ⅳ levels. at the same time
○III, ○IV Electronic balances and electronic scales are essentially the same, the difference is
Electronic balances have one more display scale than electronic scales. This small change
Change, to a great extent, has troubled many new weighing instrument verification personnel. they will found that on an electronic scale, the nameplate said it was an electronic scale, but the calibration graduation value was and the displayed graduation value are inconsistent (it is clearly stipulated in the calibration regulations for digital indicating scales calibration graduation value e = display graduation value d, but the electronic balance calibration regulations can (expanded up to 10 times), which makes it impossible for them to determine whether the instrument is electronic scales or electronic balances. This type of electronic weighing instrument is produced because the manufacturer to get good sales on my own electronic scale, I deliberately expanded the number of digits displayed.As a result, the scales on the market are different from the scales produced by the manufacturer at that time.(Some even have never done type approval or obtained a license). so when encountering this type of electronic weighing instrument, I personally recommend that you either get it calibrated and issue a certificate of failure.
(The appearance of the nameplate label does not match), or issue a calibration certificate. If school opens Calibration certificate, the reference calibration method can be an electronic balance or an electronic scale.
(2) The calibration procedures referenced by the two are different. Domestic due to the two supervisors the technical committees are inconsistent (electronic scales belong to the National Technical Committee on Weighing Instruments and Metrology)
Committee, while the electronic balance belongs to the National Technical Committee on Mass Density Measurement (under the name of the association), so there were two calibration regulations JJG539 - 1996 "Digital Indicating Scale Calibration Regulations", JJG1036 - 2008 "Electronic Balance Calibration Regulations"Procedure". But in fact, the testing methods of the two are basically the same. Inconsistently Because electronic balances have high precision, the calibration environment is relatively .The environmental requirements are higher than those of electronic scales, and they also require a certain amount of time to be turned on warm up. Another difference is that the electronic balance has an expanded one-digit display of minutes.When doing calibration tests, there is no need to use additional small weights to measure the specific error, much more convenient than electronic scale calibration.
