Operating range -70 ÷ +150ºС.
Fiber displacement sensors


Fiber displacement sensor OSD measures tension and compression. The signals from the sensors are processed by fiber interrogation monitors.


Principal advantages 

  • electromagnetic immunity;
  • high sensitivity;
  • reliability;
  • reproducibility and wide dynamic range;
  • high corrosion and radiation resistance;
  • fire safety;
  • possibility of spectral and spatial multiplexing of the sensing elements situated in the same or several different fibers;
  • significant distance to the place of measurement, small response time.
