Accuracy and Usable Range of Load Cells

This video discusses key load cell specifications including load measurement accuracy and usable range, and how understanding these concepts will help optimize your load cell inventory, load string changes, and calibration obligations – while ensuring you have complete coverage to accurately measure your full range of expected forces in compliance with testing standards. Load cell accuracy can be specified as either a percentage of the reading or a percentage of full scale. When expressed as a percentage of the reading, the error scales proportionally with the measured force. In contrast, accuracy as a percentage of full scale represents a constant error, which becomes increasingly significant at lower force readings. In this video, we use the example of Instron’s 6800 Series universal testing systems that offer a load measurement accuracy of ±0.5% of the reading down to 1/1,000th of the load cell’s capacity. We strongly recommend reviewing the testing standards you use to ensure compliance. 6800 Series Universal Testing Systems: https://www.instron.com/en-us/product...
