FBG - based temperature probe (model 313)

This page provides the main characteristics of the probe-type temperature sensors of the OSCT, OSMT and OSHT series for easy comparison.
Probe-type sensors are implemented in the form of a cylindrical tube with a standard installation connectors, which allows them to be used in industrial equipment as an alternative to electrical thermometers.
Design of probe-type sensors can be adapted to the Customer requirements while maintaining their functionality.

Advantages of the fiber temperature sensors:

  • spectral multiplexing;
  • possibility of remote measurements (no power supply requires at the measurement site);
  • long-term stability of measurements;
  • immunity to electromagnetic interference;
  • fire safety;
  • small dimensions and weight;
  • wide temperature range of measurements;
  • low error level within the entire measurement range.

 

FEATURES OF PROBE-TYPE SENSORS

  • easy installation;
  • high temperature resistant light guides;
  • compatible with most FBG interrogators from various manufacturers.

 

APPLICATIONS

Local and quasi-distributed thermal monitoring of objects, structures and systems in various fields of science and technology:

  • buildings, roads, bridges and other constructions;
  • hydro, wind, nuclear power stations;
  • cars, railway and sea transportation;
  • airplanes and space systems;
  • oil and gas industries, including pipeline monitoring.
