Load cell is an elastic member as the primary transducer and strain gauge is the secondary transducer. When this combination is used, it is called load cell. In this case an axial compressive load causes a negative strain in vertical gauges. The two strains are not equal in this case. These are related to each other by Poisson’s ratio and a force is measured.
1. It is used in aerospace, medical, and automation measurement platforms. 2. It is used to measure pressure in machine tool application. 3. It is used for weighing 4. It is used to measure torque force.
