Operating range -70 ÷ +150ºС

OSCT series

Fiber-optic temperature sensors (OSCT series) are meant for measuring temperature on various objects from -70 to +150ºС. The signals from the sensors are processed fiber interrogation monitors.

Fiber-optic temperature sensors was metrological tests in Russia. Approval certificate of measuring instruments RU.C.32.004.A  №49372.

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.
