1、 Electronic scales Electronic scales are weighing technology in a new type of instrument is widely used 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
2、 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 small label contains: na
3、me, price, weight, etc. 11 list in this small electronic label. Greatly accelerated the use of label machine sales pace, but also convenient for customers. Top barcode labels have many remarkable features of scale, Ethernet feature makes the management more convenient. Electronic Scale Classificatio
4、n (scales can be divided into mechanical and electronic type) 1 How it works: electronic works in electronic components (weighing sensor, AD conversion circuit, microcontroller circuits, display circuit, keyboard circuitry, communications interface circuits, regulated power supply circuit circuit. 2
5、 using the function: electronic weighing the use of modern sensor technology, electronics and computer technology integration, electronic weighing devices, in order to meet and solve real lifes fast, accurate, continuous, automatic weighing requirements, while effectively eliminating human error, to
6、 make it more in line with the management of legal metrology and industrial production process control applications. 3. Three health scales are weighing the use of features in a category (divided into mechanical and electronic), inexpensive, it can help people to effectively monitor their own body w
7、eight 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
8、e and subdivision standards, is subject to the protection of the national metrology products. In the electronic weighing there is a category called human scale products, which can test in the measurement sector, weighing very precise. Block diagram interpretation of the principle of electronic balan
9、ce The first part of the electronic scale principle block diagram: Program K / B (button) Fx Sensors OP Zoom A / D converter CPU display driver display memory Workflow Note: When an object on the pan when the pressure facilities to the sensor that occurred deformation, so that resistance to change,
10、while the use 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 d
11、isplay this result. Until the show such a result. The second part of the scale of the classification: 1. According to principles of points: E-scale mechanical scale mechanical and electrical integration scales 2. According to the functions sub: Counting Scales Weighing Scale Pricing Scale 3. Purpose
12、: Industrial Commercial Scales Special Scales Balance The third part of the scale types: 1. The full name of the desktop Scale refers 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
13、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 precision of 1 / 100,000 III: the accuracy of scale 1 / 1000 precision of 1 / 10000 Class IV
14、: Common Scale 1 / 100 precision of 1 / 1000 Part V of professional terminology: 1. Maximum weighing: an electron balance, excluding tare weight, the maximum load can weigh; 2. Minimum weigh: a electronic scales below the value that would have occurred when a relatively error; 3. safe load: 120% of
15、the normal weighing range; 4. Rated load: normal weighing range; 5. permissible error: class test when the maximum deviation; 6. a sense of quantity: a single electronic scales can show the smallest scale; usually d to represent; 7. analytic capacity: a function with a count of the electronic scales
