What is an Oscillator Transducer?


Oscillator Transducer Definition


An oscillator transducer is a device that converts force, pressure, or displacement into a measurable voltage.


 

 

Constituent Part


  • Mechanical linkage

  • Oscillator

  • Frequency modulator

  • Force summing member


 

 

Working Principle


It operates by using pressure to change the capacitance in a capacitor, which alters the frequency of an oscillator.

Components


The key parts include a mechanical linkage, oscillator, frequency modulator, and force summing member.

 


Advantages


  • This transducer can measure both dynamic and static phenomena, making it versatile for different applications.



  • This transducer is very useful for telemetry applications.


 

 

 

Disadvantages


  • This transducer has very hunted temperature range.



  • It has a poor thermal stability.



  • It has a low accuracy and therefore is used only in low accuracy applications.
