HOME / Principle of High-Temperature Temperature Measurement Optical Cable in Hungary - DKN Access Networks & Consulting
In temperature measurement, there is perhaps the greatest diversity of fiber optic effects that have been used, resulting from the fact that very many physical effects can be readily transduced to produce a
The usual DTS temperature measurement principle and positioning principle is R-OTDR, which uses Raman scattering. Its working principle is that Rahn scattering occurs in the optical fiber, and the
Fiber-optical thermometer Fiber-optical thermometers can be used in electromagnetically strongly influenced environment, in microwave fields, power plants or explosion-proof areas and wherever
Since Brillouin and Raman scattered lights change in frequency and intensity with change in temperature of the optical fiber, the frequency/intensity changes can be detected to measure
