FBG temperature sensor

FBG temperature sensor

The fiber optic temperature sensor FBGT-01 is a very sensitive, ruggedized indoor temperature sensor based on Fiber Bragg Grating technology. This sensor can be used alone or in series as part of
an FBG sensor array. The FBG is inside a ceramic tube.

The FBGT-01 features high accuracy and resolution, and total fiber optic design ensuring intrinsic immunity to electric sparks and EMI/RFI. Additionally it combines compact size, high resistance to corrosion with long-term reliability.


  • Temperature monitoring for single end applications or serial configuration
  • Up to 10 sensors in chain ( measurable by one channel )
  • Zero power, EMI immune, intrinsically safe
  • Broad operating temperature range
  • Multi-km signal integrity
  • High precision and excellent long-term stability
  • Fast, simple, repeatable installation


Main application is in SHM projects, where is used especially for compensation measurements to eliminate temperature effect on the sensors of mechanical strain and then applications in power industry.

Contact temperature measurements available for solid, liquid and gaseous environments. Possibility to measure in single or multiple points, sensing networks etc. Suitable for environments with electromagnetic waves, HV applications etc
