What is the accuracy of automatic weighing machine (on-line weighing machine)
The accuracy of automatic weighing machine (on-line weighing machine) refers to the value that can be displayed on the weighing equipment display, such as 35.1, the accuracy is 0.1; the display is 35.01, the accuracy is 0.01. The automatic weighing machine is mainly composed of electronic components and weighing frame, which is used to detect whether the weight of the tested products in the product production line meets the requirements or to classify the tested products according to the weight grade. However, although the accuracy of automatic weighing machine is very high, there will be errors in a certain range if it is not operated improperly. The factors that affect the accuracy of automatic weighing machine are as follows:
1. Temperature, generally high temperature, low temperature, humidity and stability will also affect the accuracy of the automatic weighing machine. In general, the suitable working environment for automatic weighing machine is-5-40 degrees Celsius, relative humidity: 0.95 (no condensation).
2. Ground vibration, due to the loud noise in the workshop, frequent operation of the machine leads to ground vibration, and even the uneven ground in some workshops will affect the accuracy of the automatic weighing machine.
3. Air flow, such as fans, air conditioners and wind blowers in the workshop, will affect the accuracy of the automatic weighing machine.
4, static induction, charged objects or dust close to metal objects will produce static electricity, of course, it will also cause interference or even damage to the sensitive automatic weighing machine, so prepare anti-static measures in advance.
5, the product has the omission phenomenon, for example, the packing box seal is not tight enough to cause the omission, this phenomenon will also have a certain impact on the accuracy. For more information on the price of weighing machines, please click on the online customer service consultation.
6. The tested product is corrosive, and only a corrosive automatic weighing machine can be customized. In the early stage, through detailed communication with the engineer, what kind of material and what kind of technology are used for special treatment.
7. Human error, improper use in the production process has a great impact on the accuracy of the automatic weighing machine, and even damage the automatic weighing machine, the weighing sensor is easy to damage.
8, radio frequency interference, all kinds of radio frequency interference automatic weighing machine. Therefore, how to reduce and avoid this kind of radio frequency interference not only has theoretical significance, but also has engineering value.

What is the working principle of automatic weighing machine?
The automatic weighing machine is composed of electronic components, weighing sensor, amplifying circuit, AD conversion circuit, single chip microcomputer circuit, display circuit, keyboard circuit, communication interface circuit, voltage stabilized power supply circuit and so on. Work flow description: when the object is placed on the scale, the pressure is applied to the sensor, the sensor is deformed, so that the impedance changes, and the excitation voltage is changed to output a changing analog signal.
The signal is amplified and output to the analog-to-digital converter by the amplifying circuit. The digital signal is converted into digital signal which is convenient for processing and outputted to CPU operation control. CPU outputs this result to the monitor according to keyboard commands and programs. Until this result is displayed.

What are the common faults of automatic weighing machine? What should we do with it?
First, the operation panel touch display screen does not display information, most likely because there are
1. The phenomenon of bad contact of switching power supply
2. The fuse in the main chassis is burnt out.
3. The charging cord of the mobile phone comes loose or falls off
Second, the software desktop display of the automatic weighing machine system is always zero, which is likely to be due to
1. The object is light and the net weight falls within the zero category, which should be dealt with according to the re-setting of the “zero category”.
2. If the weighing system feels zero, it can be dealt with according to the new item of “automatic zero tracking” in the software selection of the regulating system.
3. The charging wire of the sensor phone is loose. If you come into contact with bad phenomena, please click online customer service to know the price of the weighing machine.
Third, the tremor of data information is large, and the abnormal probability of fluctuation is due to
