Electronic scales
Electronic scales are weighing technology in a new type of instrument is
widely ud in various occasions. Electronic scales and mechanical scales have
more small size, light weight, simple structure, low price and practical value of
strong, convenient maintenance and so on can be in a variety of environmental
work, the weight of the signal can be Remote, the weight of display is easy to
implement digital, easy-to-computer network, production automation, higher labor
productivity. Scale labels in the supermarket is in the application of face value. A
勤能补拙的例子small label contains: name, price, weight, etc. 11 list in this small electronic label.

customers. Top barcode labels have many remarkable features of scale, Ethernet
feature makes the management more convenient.
Electronic Scale Classification (scales can be divided into mechanical and
electronic type)
1． How it works: electronic works in electronic components (weighing
nsor, AD conversion circuit, microcontroller circuits, display circuit, keyboard
circuitry, communications interface circuits, regulated power supply circuit circuit.销售部管理制度
2． using the function: electronic weighing the u of modern nsor
technology, electronics and computer technology integration, electronic weighing
devices, in order to meet and solve real life's "fast, accurate, continuous,
automatic" weighing requirements, while effectively eliminating human error, to
make it more in line with the management of legal metrology and industrial
production process control applications.
3.
Three health scales are weighing the u of features in a category
(divided into mechanical and electronic), inexpensive, it can help people to
effectively monitor their own body weight changes, new products also can detect
their fat content, but also Some human-oriented subsidiary functions. May not be
part of measuring equipment.
4． Electronic Scale is a measurement of the state compulsory test apparatus,
and his qualified products are test indexing the value of D values of e and
subdivision standards, is subject to the protection of the national metrology奥龙虾图片
products. In the electronic weighing there is a category called "human scale"
products, which can test in the measurement ctor, weighing very preci.
Block diagram interpretation of the principle of electronic balance
The first part of the electronic scale principle block diagram:
Program K / B (button) ↑ Fx → Sensors → OP Zoom → A / D converter →
题竹石
CPU → → display driver display memory
Workflow Note: When an object on the pan when the pressure facilities to the
nsor that occurred deformation, so that resistance to change, while the u of
excitation voltage changes, the output of a change in analog signal. This signal
amplification by the amplifier output to the ADC. Converted to facilitate the
processing of the digital signal output to the CPU operator control. CPU under the
keyboard commands and program output to display this result. Until the show such
a result.
The cond part of the scale of the classification: 1. According to principles
of points: E-scale mechanical scale mechanical and electrical integration scales 2.红孩儿大话火焰山
According to the functions sub: Counting Scales Weighing Scale Pricing Scale 3.
Purpo: Industrial Commercial Scales Special Scales Balance
The third part of the scale types: 1. The full name of the desktop Scale refers
微笑局长
to the volume of less than 30Kg electronic scale 2. The full name of platform scale
refers to the volume within the 30-300Kg Electronic Scale 3. Loadometer full
name refers to the volume of more than 300Kg Electronic Scale 4. Precision
Balance
4th Part of the accuracy of classification: I Class: Special scales precision ≥ 1
/ 10 Wan II level: high-precision scale 1 / 10000 一周健身计划≤ precision of "1 / 100,000 III:
the accuracy of scale 1 / 1000 ≤ precision of "1 / 10000 Class IV: Common Scale 1
