Keysight Technologies Load-Cell Testing in Practice Application Note What is a Load-Cell? A load-cell is a device that is used to measure high compression, tensile force, high pressure, and weight. Load-cells take many forms in order to accommodate a variety of uses in research and industry applications. Most current designs use a strain gauge as the sensing element because it is able to measure tension, compression, and shear forces.
