Electronic Scale Types
Workflow Description:
When the object is placed on the weighing pan, the pressure is applied to the sensor, the sensor deforms, so that the impedance changes, and the excitation voltage changes, and a changing analog signal is output. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter. Convert it into a digital signal for easy processing and output it to the CPU for operation control. The CPU outputs such results to the display according to keyboard commands and programs. until this result is displayed.
Classification of scales:
1. According to the principle: electronic scale mechanical scale electromechanical combined scale
2. According to function: counting scale, pricing scale, weighing scale
3. By use: Industrial scales Commercial scales Special scales
Types of scales:
1. Desktop scale refers to an electronic scale with a full weighing below 30Kg
2. Platform scale refers to an electronic scale with a full weighing range of 30-300Kg
3. Floor scale refers to an electronic scale with a full weight of more than 300Kg
4. Precision balance
Sort by Accuracy:
Class I: special balance precision ≥ 1/100,000
Class II: High-precision balance 1/10,000≤precision<1/100,000
Class III: medium precision balance 1/1000≤precision<1/10000
Level IV: Ordinary scale 1/100≤precision<1/1000
