In today Session I Am going to discuss about Most useful sensor in Automation field. In Last Post we seen Sensor Like float. but in thus post we will Discuss Proximity Sensor. What is Proximity Sensor? Proxy- means Near, Proximity Sensor will Detect the Near by Object without any physical touching within the given Range.(here given range define on selection of Sensors detection range). A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation( refers to Wave or light) . The proximity sensor is a very useful device. Some examples of proximity sensor uses. 1.It is used in machine vibration monitoring to variation in distance between a shaft and its support bearing. 2. it is used to Detect metallic object 3. it used in Food Industry 4. Its used in Packaging Industry etc. There are Four...
