Q1 (a) Measurement systems plays a crucial role in industrial automation. Elaborate how the measurement systems help the automated systems to achieve superior performance in comparison to a manual system. (b) Elaborate on the factors that need to be considered when choosing a suitable instrument of measurement system for certain applications. (c) Figure Q1 shows an example of data sheet of a type “S” load cell. The load cell is used to measure a tensional force that is applied to it. Elaborate on the applied sensor technology and its working principle by the help of appropriate illustration. Type “S” Load Cell TENSION FORCE DI ARTECH vori Ind.
