Transducers by bhushan kumbhalkar

  1. 1. By BHUSHAN KUMBHALKAR
  2. 2. Introduction  A transducer is a device that converts energy from one form to another for various purposes like measurement or Information transfer eg.,Pressure sensors.  Device which converts one physical quantity or condition to another  Physical quantity – heat , intensity of light, flow rate, liquid level, humidity etc
  3. 3. Transducer (conversion)Any measureable quantity in Anything out eg. any measurable quantity: • energy: sound, electrical, mechanical, light, chemical, • pressure, level, density, temp, pH, flow, temperature • position, distance, mass, time • etc, etc. eg. any measurable quantity: • energy: sound, electrical, mechanical, light, chemical, • pressure, level, density, temp, pH, flow, temperature • position, distance, mass, time • etc, etc.
  4. 4. Classification of transducers usable values real world analog signal primary transducer secondary transducer sensor actuator
  5. 5. LVDT Use along with bourdon tube & bellows to determine the displacement , pressure etc
  6. 6. Classification of transducers  There are many ways to classify transducers:  By what they are measuring  General classification.  Specific classification.  By the output signal type.  By whether or not they produce their own supply. (Active or Passive)  Input to output.  Contact type or not  Direct or indirect.  Method used to sense input.
  7. 7. BELLOWS
  8. 8. Thermister
  9. 9. Temepeture sensing circuit Used for air-coditionar , motors etc
  10. 10. LDR (Light Dependent Resistors)
  11. 11. Light sensing Circuit
  12. 12. DIPHRAGM Use to sense pressure ,temperature etc
