What are the factors that affect the accuracy of automatic weighing machines
1) Connotation factor of the tested item 1. The properties of the tested item include liquid, solid and powder. When the liquid object enters the weighing platform, because the conveyor belt of the weighing platform is moving, the shaking of the liquid inside will cause the change of the center of gravity of the object; 2. The packaging of the tested object includes bags, cans and bottles. The size of the weight tolerance between the same packaging, the flat bottom of cans and bottles, the size of the bottom diameter, 3. The material of the tested item, transparent items and reflective items will affect the induction of the photoelectric switch; but we use no photoelectric component. Identifying patterns to check weighing can be useful to prevent this confusion. 4. The weight of the tested item, the heavier the item, the lower the accuracy. 5. The speed of the item to be tested, the faster the belt speed, the shorter the reading time of the system, the greater the impact on the accuracy; the number of detected items per minute will also affect the accuracy. 6. The shape of the object to be tested, the uneven bottom surface of the special-shaped object, and the vibration when entering the weighing platform has a great impact on the accuracy. (2) Use environmental factors 1. The temperature and humidity of the operating environment; 2. The vibration of the ground and the air flow, the vicinity of the machine with large vibration, and the air outlet of the fan and the air outlet of the air conditioner, it is not suitable to install the checkweigher machine; 3. Static electricity and electromagnetic interference , the equipment should be grounded, and it should be separated from the high-power equipment and power supply system; 4. Protective measures should be taken in places with large dust and corrosive liquids. (3) Human factors 1. Improper parameter setting during use; 2. The distance between the speed-up section, automatic weighing section and the rejection section of the machine is too large or too small; 3. The weighing platform is not level; 4. The conveyor belt is too loose or too tight; 5. The motor wire and sensor wire are not tied properly; 6. The sensor is overloaded and damaged; 7. The reflector of the photoelectric switch is not cleaned in time.

If something seems too good to be true, then it can be a , which provides linear weigher value over its cost.
Overwhelming customers with too much information or the slew of benefits weigher provides–even if they're all valid–is a surefire way to lose their attention.
