How to Obtain Accuracy of Load Cell-Based Weighing System

To obtain the accuracy of an electronic load cell-based weighing system, load cell installation quality and errors due to vibration, etc. should be considered together with intrinsic errors of load cell and amplifier and ambient temperature change. Here, we explain the method of calculating the system accuracy by taking the case where static errors of load cell and amplifier are main factors affecting the system accuracy. Obtain the accuracy of the detecting system including the load cell and the accuracy of the amplifier. Then, obtain the system accuracy by calculating the square root of the sum of their squares.
