In comparison with the conventional types, fiber optic sensors are used in wide range areas such as physical, chemical, bio-medical, oil and gas applications. Different measurements can be made with high accuracy and optimal reliability such as strain, rotation, displacement, temperature, pressure, velocity, acceleration, electrical and magnetic fields.

Advantages of Fiber Optic Sensors over conventional sensors

  • Nonelectrical, Explosion proof.
  • Often do not require contact.
  • Remotable.
  • Allow access into normally inaccessible areas.
  • Potentially easy to install.
  • Immune to radio frequency interference (RFI) and electromagnetic interference (EMI).
  • Solid state reliability.
  • High accuracy.
  • Can be interfaced with data communication systems.
  • Secure data transmission.
  • Resistant to ionizing radiation.
  • Can facilitate distributed sensing.
  • Can function in harsh environments.
