The electronic scale is an automatic weighing equipment used to weigh the goods. Through the power and electricity conversion of the sensor, the measurement of the goods is completed through the processing of the weighing instrument. It is suitable for the measurement of various bulk goods. working principle:

The weighing items are converted into analog signals of voltage or current through the weight sensor installed on the mechanism, and after amplification and filtering, the A/D processor converts them into digital signals, and the digital signals are calculated by the central processing unit (CPU). Processing, and the functions required by the peripheral and various interface circuits are also connected to the CPU for application, and finally displayed digitally by the display screen.

Main components:

1. Weight sensor 2. Amplifier circuit 3. Filter circuit 4. Analog-to-digital converter 5. Central processing unit 6. Power supply circuit 7. Button 8. Shell 9. Mechanism 10. Weighing pan

Jw-214 White Digital Plastic Kitchen Scale

Electronic pricing scale: It is composed of high-precision resistance strain load cell, load-bearing device and weighing display.

The analog voltage output by the sensor that is proportional to the weight of the object to be weighed is filtered out by the filter and then converted into a digital quantity by an analog/digital converter. and amount are displayed. The electronic pricing scale can pre-set the unit price and automatically display the amount of the item being weighed while weighing. It is a commercial scale that integrates weighing, pricing, display, tare, and printing.

It has the characteristics of high measurement accuracy, convenient and fast keyboard operation, and has functions such as digital memory.

When the key cannot be pressed, the key can be locked to avoid misoperation. There are three types of maximum weighing/minimum division value of pricing electronic scale: 3kg/1g, 6kg/2g and 15kg/5g.
