Sensors and transducers

  1. 1. SENSORS & TRANSDUCERSBy: Nikhila Wakle Preeti Bhat Anish Das Mitul Pimpale
  2. 2. TRANSDUCERS A device which converts 1 form of energy into another. In a process industry 4 basic and very important parameters to be measured and controlled are: 1) Flow 2) Temperature 3) Pressure 4) Level
  3. 3. FLOW MEASUREMENT
  4. 4. TEMPERATURE MEASUREMENT•Thermocouple•Thermistor•RTD•Bimetallic Thermostat•Pyrometers
  5. 5. COMPARISION OF DIFFERENTTYPES OF TEMPERATURESENSORS
  6. 6. PRESSURE MEASUREMENT Manometric Method Elastic Pressure Transducers 1) Bourdon Tube 2) Bellows 3) Diaphragms 4) Capsule Electric Pressure Transducers 1) Capacitive e.g. D.P. Cell 2) Inductive e.g. LVDT
  7. 7. PRESSURE GAUGE Generally named as Pressure gaugesor Vacuum gauges.Absolute pressure is zero-referencedagainst a perfect vacuum, so it is equal togauge pressure plus atmosphericpressure.Gauge pressure is zero-referencedagainst ambient air pressure, so it is equalto absolute pressure minus atmosphericpressure.Differential pressure is the difference inpressure between two points
