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 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: name, 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 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, display 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 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 use 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 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 balance

The first part of the electronic scale principle block diagram:

Program K / B (bu tton) ↑ 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, 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 display 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: 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 refers to the volume of more than 300Kg Electronic Scale 4. Precision Balance

4th Part of the accuracy of classification: I Class: Special sca les 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: 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 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, can distinguish the smallest scale; 8. Resolution: a counting function with an electronic scale, the internal capacity of a Resolution of a parameter; 9.

Warm-up time: a scale used to achieve the targets of the time; 10. Accuracy: The full name of a sense of volume and volume ratios; 11. electronic scale use of environmental temperature: -10 degrees Celsius to 40 degrees Celsius 12. platform scale The table size: 25cm X 30cm 30cm X 40cm 40cm X 50cm 42cm X 52cm

45cm X 60cm

Part VI electronic scale features: 1. To achieve long-distance operations; 2. To achieve automatic control; 3. Figures show that an intuitive, reduce human error; 4. High accuracy and resolution strong; 5. Weighing range is wide; 6 . unique features: buckle weight, withholding weight, zero, accumulated, warning, etc.; 7. maintenance simple; 8. size is small; 9. installation, calibration simple; 10. special industry, can be accessed by the printer or computer-driven; 11. Intelligent electronic scale, quick reaction, high efficiency; Part VII of the electronic scale
