1、Electronic scalesElectronic 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,

2、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-

3、computer network, production automation, higher labor productivity. Scale labels in the supermarket is in the application of face value. A small label contains: name, price, weight, etc. 11 list in this small electroni

4、c 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. Ele

5、ctronic Scale Classification (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, displ

6、ay circuit, keyboard circuitry, communications interface circuits, regulated power supply circuit circuit. 2. using the function: electronic weighing the use of modern sensor technology, electronics and computer technol

7、ogy 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

8、 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), inexpens

9、ive, 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

10、. 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

11、 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 elect

12、ronic balance 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 (liquid crystal display): free elec

13、tricity, energy-saving, with backlight; 2.LED: free electricity, power consumption, very bright; 3. Lamp: electricity, power consumption , high; K / B (button) type: 1. film button: contact type; 2. mechanical buttons:

14、 made up of many individual combinations of keys together; sensor characteristics: 1. rated load; 2. output sensitivity; 3. non-linear; 4. hysteresis; 5. repeatable; 6. creep; 7. 12:00 output effects; 8. rated output

15、temperature; 9. 12:00 input; 10. input impedance; 11. output impedance; 12. Insulation Resistance ; 13. to allow excitation voltage; (5-18V) Part IX sensor damaged phenomenon: 1. Weighing not allowed; 2. Shows no retur

16、n to zero; 3. Shows the number of bounce to judge the sensor + E,-E, + S,-S 1. The first to use resistance profile measurement 4-line 22 This resistance value, a total of 6 groups. The case of 400-450, compared with Eu

17、rope + E,-E; if it is 350 in Europe, compared to + S,-S; for the 290 in Europe, compared to R-arm; 2. + E,-E terminated on the + 1.5V voltage Sensor correctly to exert a pressure, such as the output + _S increase, then

18、 the red table pens as + S, the contrary-S; 10th part of the high-precision counting scale features: 1.Kg/Ib unit conversion functions; 2. 12:00 display range adjustment function (GLH series does not) 3. Sampling spee

19、d adjustment function; 4. There are 10 groups memory function singlet; 5. may be at the same time the weight, quantity, the cumulative function (GLH only the number of cumulative) 6. can set the weight, the maximum am

20、ount of warning function; 7. automatic zero tracking, temperature linear correction; 8. deduction of withholding heavy weight and function; 9. Standby function; 10. there is zero shows zero tracking range and scope; 11

21、. there is the battery voltage control to limit the function; Electronic scales are weighing technology in a new type of instrument is widely used in various occasions. Electronic scales and mechanical scales have mor

22、e 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 d

23、isplay is easy to implement digital, easy-to-computer networking, process automation of production and improve labor productivity. Electronic Scale also has an automatic zero tracking, overload display of self-extingu

24、ishing characteristics. Mechanical scales, floor scale / land in the value (car value), weigh-bridges and other fitted force-sensitive sensors and microcomputer-controlled intelligent weighing instruments become intell

25、igent digital electrical and mechanical balance (or the mechanical and electrical dual-use scales), to improve the mechanical balance of the measurement accuracy, with low cost, high reliability, simple installation an

26、d so on, without prejudice to the original mechanical scales to any transmission bearing structure. There are peeled, set to zero, the cumulative number of times, the cumulative weight (cumulative amount of valuation-

27、based), auto-zeroing, auto-tracking and other functions. Weighing data can be directly printed or transmitted via computer networks, industrial processes can improve the level of scale and product quality, trade cleari

28、ng with the scale can improve the credibility of incalculable social and economic benefits. Electronic Scale is basically a sensor, amplifier circuit, A / D conversion circuit, microcontroller control of display parts,
