Sensitivity = (6V * 2.1 * 100) / (40mm * 200 GN/m2 * 0.29)
= 0.0045 V/KN
A load cell consists of a solid cylinder of steel 40 mm diameter with four strain gauges bondedto it and connected into the four arms of a voltagesensitive bridge. the gaugesare mounted to have poisson's arrangement. if the gauges are each of 100 resistance and the gauge factor 2.1, the bridge excitation voltage 6V, determine the sensitivity of the cell in V/KN. Modulus of elasticity for steel is 200 GN/m2 and poissons ratio is 0.29
