  1. 1. A SEMINAR PRESENTATION ON SUMMER TRAINING Bachelor of Technology in ELECTRICAL ENGINEERING session : 2013-2014 in care of Mewar University Presentation by Yogesh.R IV Year , EE
  2. 2. Training in Undertaken at I.D.E.M.I , Mumbai INDUSTRIAL AUTOMATION
  3. 3. • Manpower cost – by reducing manpower • Utility cost – by power saving • Quality improvement – Through good control • High production – Through state of art machine • Keeping proper record – Through system In today’s scenario production cost is increasing rapidly. The labour cost, raw material cost, power cost, etc. are not in our control. Hence to increase the productivity and reduce the production cost we can only have controls on : All these can be possible only by implementing AUTOMATION INTRODUCTION
  4. 4. AUTOMATION A STEP AHEAD MECHANIZATION Automation is basically the delegation of human control function to technical equipment or Automation is the use of control systems and information technologies reducing the need of human intervention
  5. 5. IMPACT OF AUTOMATION • Achieve more with less time • Elimination of human error • Cleaner Technology • Minimize Energy consumption • Easy diagnosis of fault • Effective application for Complex tasks • Improve Safety and Health • Increase in productivity by achieving the optimum efficiency of the machine.
  6. 6. Main body of automation • PLC • SCADA • Drives • Sensors
  7. 7. Sensor Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example:- temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically.
  8. 8. Sensor are basically consists of three parts: • Transducer • Processing circuit • Driver circuit
  9. 9. Classification of Sensors Active Sensors Passive Sensors Active sensors operate under energy conversion principles also self-generating type, develop their own voltage or current .They generate an equivalent output electrical signal without any external power signal The Passive sensors operate under energy controlling principle. In this case the case the process parameter is converted into passive parameter such as resistance, capacitance or inductance that need an auxiliary supply so as to get an electrical output.
  10. 10. PROXIMITY SENSOR The Passive sensors operate under energy controlling principle. In this case the case the process parameter is converted into passive parameter such as resistance, capacitance or inductance that need an auxiliary supply so as to get an electrical output. • Inductive Sensor • Capacitive Sensor • Optical Sensor • Ultrasonic Sensor • Magnetic Sensor Types Of Proximity Sensors
  11. 11. INDUCTIVE SENSOR • Sense the presence of metallic object. • Used for position sensing , counting speed
  12. 12. Capacitive sensor • Detect any target whose dielectric is more than air • Also used to detect fluids • Used for position level of liquids.
  13. 13. Optical sensor • Optical sensor has 2 parts : Emitter & Receiver • Three types of optical sensor : Thru beam , Diffused type , Retro- reflective type
  14. 14. 1) THRU BEAM transmitter receiver • Consist of 2 parts : Transmitter & receiver , both are kept apart facing each other •Main disadvantage : need auxiliary power supply for separate units target
  15. 15. transmitter receiver target After the interruption of target, receiver gives a signal which is amplified and fed into output of sensor THRU BEAM
  16. 16. 2) DIFFUSED TYPE • Transmitter & receiver placed together • When there is no target , sensor switches its off • More convenient than Thru beam • Does not work well in transparent target
  17. 17. DIFFUSED TYPE After the interruption of target , target reflect those light pulses to receiver
  18. 18. 3) Retro-reflective • Both are placed together • Reflectors are used
  19. 19. After the interruption of target , target reflect those light pulses to receiver Retro-reflective
  20. 20. Ultrasonic sensor • Sense any material solid or liquid • Dust resistant • Long sensing gap
  21. 21. MAGNETIC SENSOR • Actuated by magnetic field • Application : Pneumatic & Hydraulics • When mag. switch senses mag. field , it will give switching signal
