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.
