Operating range -70 ÷ +350ºС

OSSH series

The fiber strain sensors (OSSH series) makes use of the sensitivity of fiber grating to measure the strain from -70 to +350ºС. 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.
