Changzhou Zhuoyue Automation System Co., Ltd. supplies automatic checkweighers and automatic Weighing Machines. Both of these are high-precision and high-speed Weighing equipment and are highly favored in industries such as food, pharmaceuticals, and light industry. The following are some small insights summarized from years of checkweigher manufacturing. We will introduce in detail the eight factors affecting the accuracy of automatic Weighing Machines to help everyone use automatic weighing machines better. 

Eight factors affecting the accuracy of automatic weighing machines: 

1. Air flow: Air flow conditions such as fans, air conditioners, and natural winds in the workshop will all affect the accuracy of weight Sorting scales. For example, strong winds may cause deviations in weighing results.

2. Ground vibration: The noise in the workshop is loud, and frequent operation of machines may cause ground vibration. Even some workshop floors are uneven, and these situations will affect the accuracy of weight Sorting scales. Ground vibration will interfere with the weighing sensor, thus affecting the accuracy of measurement results. 

3. Temperature: High temperature, low temperature, humidity, and extreme temperature changes will all affect the accuracy of weight sorting scales. Generally, the suitable working environment for weight sorting scales is from -5°C to 40°C, and the relative humidity is 95% (without condensation). Under temperature conditions outside this range, the performance of weighing equipment may be affected. 

4. Electrostatic induction: When a charged object or dust approaches a metal object, static electricity will be generated. Static electricity may interfere with or even damage sensitive weight sorting scales. Therefore, corresponding preventive measures such as grounding and using anti-static materials are needed. 

5. Radio frequency interference: Various radio frequencies may interfere with automatic weighing machines. Reducing and avoiding this radio frequency interference has important theoretical significance and engineering value. Methods such as shielding and filtering can be used to reduce the influence of radio frequencies on weighing machines. 

6. Corrosiveness of the tested product: If the tested product is corrosive, a customized weight sorting scale with corrosion resistance is needed. In the early stage, detailed communication with engineers should be conducted to determine which materials and processes are used for special treatment to ensure that the weighing machine can accurately measure in a corrosive environment. 

7. Product omission phenomenon: For example, if the product is omitted due to poor sealing of the packaging box, this seemingly minor phenomenon will also have a certain impact on accuracy. Product omission may lead to inaccurate weighing results because the object being weighed has changed. 

8. Human error in use: In the production process, improper human use has a greater impact on the accuracy of weight sorting scales and may even damage the weight sorting scales. Among them, the weighing sensor is more easily damaged by human error. Therefore, operators should receive professional training and use weighing equipment correctly to ensure measurement accuracy and the service life of the equipment.
