Introduction – Role of sensors in manufacturing automation – operation principles of different sensors – electrical, optical, acoustic, pneumatic, magnetic, electro-optical and vision sensors. Condition monitoring of manufacturing systems – principles – sensors for monitoring force, vibration and noise, selection of sensors and monitoring techniques. Acoustic emission – principles and applications – concepts of pattern recognition. Sensors for CNC machine tools – linear and angular position and velocity sensors. Automatic identification techniques for shop floor control – optical character and machine vision sensors – smart / intelligent sensors – integrated sensors, Robot sensors, Micro sensors, Nano sensors. Manufacturing of semi conductor sensors and fibre optic sensors – principles, applications.
