A survey on sensor classifications for industrial applications

The importance of sensors in industrial applications is a result of the introduction of many robotics, automation, and intelligent control techniques into factory floors. Research and improvements need to be continuously performed to meet the challenges in automation and manufacturing applications in industry. Manufacturing processes are becoming extensively dependent on robotic and automation systems, and are requiring more reliable and accurate sensors to be integrated with the manufacturing systems. Sensors are selected depending on the type of process, the expected precision, the operational environment, and many other factors. In this report we survey the different classifications of sensors, and the various sensor applications in industry.
