Electronic scales are primarily classified based on three dimensions: function, application, and weighing capacity. Common types include weight-only scales, price-computing scales, bench scales, and floor scales (weighbridges).
1. By operating principle: Electronic scales, mechanical scales, and electromechanical scales
2. By function: Counting scales, price-computing scales, weighing scales, and Bluetooth scales
3. By application: Industrial scales, commercial scales, and specialty scales
4. By placement/size:
Bench scales (or tabletop scales): Electronic scales with a full capacity of under 30 kg
Platform scales: Electronic scales with a full capacity between 30 kg and 300 kg
Floor scales (weighbridges): Electronic scales with a full capacity exceeding 300 kg
Precision balances
5. By accuracy class:
Class I: Special-purpose balances; precision ≥ 1/100,000; reference weighing instruments
Class II: High-precision balances; 1/10,000 ≤ precision < 1/100,000; precision weighing instruments
Class III: Medium-precision balances; 1/1,000 ≤ precision < 1/10,000; industrial and commercial weighing instruments
Class IV: Ordinary scales; 1/100 ≤ precision < 1/1,000; coarse weighing instruments
6. By data transmission method:
RS-232/RS-485, RF (2.4 GHz), analog signal, Bluetooth, USB interface, and Ethernet.
