What is online checkweigher accuracy

Misunderstanding of accuracy: Many people easily interpret the allowable error range of the actual product as the accuracy of the checkweigher, and it is easy to ignore the error between each qualified product, for example: the allowable product error range is plus or minus 1g, the standard product weight It is 50g. Products higher than 51g and lower than 49g need to be eliminated. Then we need to know whether the error between each product of qualified products will be greater than 1g. If the error between products is greater than 1g, then there will be many unqualified products. , If the error is small, then the accuracy of our checkweigher machine must not be greater than or equal to plus or minus 1g. The accuracy error of the checkweigher refers to the accuracy in the case of dynamic weighing. If the error of the checkweigher is positive If it is negative 1g, then many qualified products will be rejected. The error of the weigherplus the error between the products themselves makes the checkweighing meaningless. Therefore, in this case, the requirements for the checkweigher machine must be higher. The accuracy of the weigheris ideal within ±0.2g, and the accuracy will be higher! When the actual weight is 51g, one of the values u200bu200bof 50.8, 50.9, 51, 51.1, and 51.2 will appear during dynamic weighing, so our upper limit should be set to 51.2, so as to ensure that products with an actual weight of 51 will not be Removal, only products higher than 51g will be rejected. If the error is large, there will be more possible values, the accuracy rate will be lower, and there will be more products that are wrongly rejected. picture:
