Fiber-Optic Temperature Measurement

Use a Single Glass Fiber at the Same Time as a Signal Path for Thousands of Spots

Glass fibers are robust, suitable for everyday use and easy to lay due to their small diameter. The systems appear to be superior in situations where the weight or a high level of flexibility is what counts to reach inaccessible places or where you would like many spots distributed across the fibers. A single fiber weighing just a few grams can therefore contain hundreds of sensors and serve as a signal path at the same time. Temperature profiles, for example, also provide you with support in

  • process monitoring in tube reactors (process engineering)
  • performing core drilling (geodesy) analyses
  • detecting leaks in cable shafts or on pipelines (safety engineering, fire protection)

Glass fibers are completely insensitive to electromagnetic radiation such as HF waves or microwaves. So, unlike electrical systems, they can also be used at high voltage potentials without any risk and can be used no bother both in potentially explosive atmospheres and in chemically aggressive environments.

The single-point sensor, which is located at the tip of the fiber as a low-cost solution, is characteristic especially for temperature measurement.
