Description: Load cells utilize an elastic member as the primary transducer and strain gauges as secondary transducers. Strain gauges may be attached to any elastic member, on which there exists a, suitable plane area to accommodate them. This arrangement may then be used to measure loads applied to deform or deflect the elastic member, provided that the resultant strain is large enough to produce detectible outputs. Fig. above shows a column type load cell mounted with four strain gauges on its periphery. The output voltage measured across the four arm Wheatstone bridge circuit, is a measure of the weight being applied.
