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.
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.
