“…In this method, the natural frequencies of the two load cells do not match (there exists a difference in dynamic characteristics), which may adversely affect the measurement accuracy. Hence, by applying the principle of relative compensation, it has been shown to improve the accuracy of mass measurement [3]. In addition, it takes 40 ms to identify on-line in this method, and high-speed mass measurement is difficult.…”

Checkweighers, that can measure the mass of a target object continuously while conveying the object on a belt conveyor, are affected by environmental vibration. As a result, accuracy of the mass measurement gets worse. To solve this problem, we have proposed a method that can eliminate the effect of the environmental vibration. This paper enhances the proposed method and improves the performance of the proposed method.

The checkweigher is a device that measures mass continuously and it carries out mass measurement while conveying an object on a belt conveyor. It is a device that operated an active role in various fields such as food, medicine, and industrial products. Although the load cell scale is often used to measure measurement in the checkweigher, due to the structure of load cell, the accuracy is susceptible to environmental vibration. It is difficult to generate low frequency input such as floor vibration with the general vibration exciter. We first manufactured a device that can reproduce environmental vibration. In this study, we present the response of the load cell to excited by the device, moreover consider the vibration compensation using an acceleration sensor.
