Fiber optic temperature sensors primarily utilize the principle that the absorption spectrum of certain substances changes with temperature. They analyze the spectrum transmitted by optical fibers to determine real-time temperature.
They are resistant to electromagnetic interference, compact in size, corrosion-resistant, shock-resistant, and capable of measuring multiple parameters.
Optical fiber temperature sensor has a wide range of applications, particularly in the medical and power systems sectors. The following section details specific application areas for fiber optic temperature sensors.
Applications of Optical Fiber Temperature Sensors
Power Systems
Due to their electromagnetic interference resistance, optical fiber temperature sensors are ideal for use in environments such as power plants and substations.
They are widely used in generators, transformers, motors, and high-voltage power distribution equipment. They accurately monitor internal temperatures in real time to prevent short circuits and fires.
Medical
In some minimally invasive surgeries, optical fiber temperature sensor can leverage their compact size to easily be inserted into the body through catheters or endoscopes. They are used for temperature monitoring during surgery, providing doctors with timely diagnostic information. The FOT-M fiber optic temperature sensor is a specialized product for medical applications.
Building Structural Inspection
Fiber optic temperature sensors offer strong corrosion resistance and can be easily embedded in concrete, steel, or complex structures. They track temperature distribution within concrete in real time, ensuring proper moisture retention and preventing cracking caused by curing.
Aerospace
Due to their compact size and ability to withstand harsh environments, they are ideal for monitoring critical components such as jet engines, composite structures, and hydraulic systems, providing accurate data with minimal risk of failure.
