Sensors Approach to Industrial Automation – A Theoretical Study

Accurate monitoring and process control based on conditions is the main aim of any automation system. Real time monitoring and control, safety enhancement, security, increased efficiency etc. are some of the aspects behind an automation. To monitor the process and to provide real time data, a sensor plays an important role in an automation. Sensors provides a data or real time condition of particular parameters under test or status of any inputs. On the basis of that information or data from sensors, the designed system of any application can control the process. As per the applications need, various sensors are available. In this paper an attempt is made to cover some basic information of sensors used in an industrial automation, their use and benefits.
