Introduction
A load cell is a transducer used to convert a physical quantity (force) to electrical quantity (voltage). A strain gage is one of the commonest types of load cells. In these types of load cells, gages are connected to a structure that bends on the application of a force. A Wheatstone bridge circuit is a four type strain traducer that gives a maximum sensitivity as well as temperature compensation (Westwood 38). A quarter or half bridge are used to perform the same purpose. In the Wheatstone bridge device, two gages are under tension while the other two are in ...
