Electronic Balances are indispensable measuring tools in modern scientific experiments and industrial production, and they are classified according to many aspects such as use, operation mode, balance principle, structural characteristics and accuracy level. These classifications enable electronic balances to provide accurate and reliable measurement results in a wide range of fields and applications.
1. Classification by use
1. General purpose balances
It is used for high-precision or medium-precision quality testing such as daily chemical analysis, physical analysis, industrial quality control, etc.
Analytical Balances:For precise analysis, including constant, semi-micro, micro and ultra-micro balances.
Industrial and Physical Balances:It is used for general quality testing with relatively low accuracy.
2. Special balance
Limited to specific applications, such as standard balances (for mass calibration), gold test balances, carat balances, animal balances, each designed for specific measurement needs.
2. Classification according to the mode of operation
Non-automatic balances:Balances that require operator intervention to take measurements.
Automatic Balance:Balances that require no operator intervention during the measurement process, automatically perform measurements and recordings.
3. Classification according to the principle of balance
1. Principle of leverage balance
Lever balances, for example, use the lever principle for mass measurement.
2. The principle of elastic force balance
These include torsion balances, spring balances, strain gauge balances, hydraulic balances, and the use of elastic elements for mass measurement.
3. The principle of hydrostatic equilibrium
For example, barometric balances and liquid static balances measure mass through the static equilibrium of fluids.
4. The principle of electromagnetic force balance
Including magnetoelectric electronic balances, magnetic suspension electronic balances, the use of electromagnetic force to achieve high-precision quality measurement.
5. Inertial measurement principle
For example, an inertial balance uses the inertia of an object to measure its mass.
Fourth, according to the structural characteristics of classification
Lever balances – are available in both mechanical and electronic formats for quality measurement with different accuracy requirements.
Elastic force balances – according to the different types of elastic elements, they are divided into torsional, spring, strain, etc., which are suitable for various measurement needs.
Hydrostatic balance balances – available in both undamped and electronic versions for accurate measurement of liquid mass.
Electromagnetic force (electronic) balances - according to the measurement principle and accuracy requirements, they are divided into capacitive, inductive, magnetoelectric, magnetic suspension and other types.
Inertial balances – are available in both mechanical and electronic forms for mass measurements that require extreme precision.
5. Classification according to accuracy level
Class I:High-precision class for balances with special accuracy requirements.
Class II:Precision class for high-accuracy laboratory and industrial applications.
Class III:Commercial balances for general industrial and commercial use with medium accuracy.
Level IV:Ordinary balances for general mass measurement and everyday applications.
