Inductive Transducer for Motion Measurement
- 2. WHAT DO YOU MEAN BY TRANSDUCER???? •A transducer is a device that converts one form of energy to another. • While the term transducer commonly implies the use of a sensor/detector, any device which converts energy can be considered a transducer. Transducers are widely used in measuring instruments.
- 4. WHAT IS INDUCTIVE TRANSDUCER????? In inductive transducer, magnetic characteristics of an electric circuit changes due to motion of object A simple type of displacement sensor is the variable inductance type wherein the variation of inductance as a function of displacement is achieved either by variation in mutual inductance or self inductance
- 5. SELF NON-SELF GENERATING GENERATING
- 6. : •A voltage signal is generated in the transducer, because of relative motion of the conductor and a magnetic field. EXAMPLE: 1. ELECTRODYNAMIC 2. ELECTROMAGNETIC 3. EDDY CURRENT TYPE ,etc.
- 9. : Also called as external power source of transducers, in which an external source is needed to energise coils, the inductance of which would change due to motion of the object. 1. LVDT type 2. Air gap type 3. Attachment type inductance transducer, etc.
- 16. Where, f=excitation signal frequency Ip=primary current Np=nos of turns in primary Ns=nos of turns in secondary b= width of primary coil w= width of secondary coil x= core displacement r0= outer radius of the coil ri = inner radius of the coil
