The full name of fiber optic temperature measurement is fiber optic temperature measurement, which can be mainly used in power equipment. It provides fluorescence fiber optic temperature measurement, mesur tymheredd ffibr optig dosbarthedig, and fiber Bragg grating temperature measurement. Mae'r pris yn rhesymol, please feel free to contact us.

The distributed fiber optic temperature sensing system can continuously measure the temperature along the fiber optic cable, with a measurement distance of several thousand meters and a spatial positioning accuracy of meters. It can perform uninterrupted automatic measurement and is particularly suitable for applications that require large-scale measurement. The traditional method for measuring temperature in distributed fiber optic temperature sensing systems is to use Stokes light to demodulate anti Stokes light, Hynny yw, to obtain the intensity ratio of anti Stokes light to Stokes light, and then compensate for the attenuation of the intensity ratio signal.

Defnyddir technoleg mesur tymheredd ffibr optig dosbarthedig yn eang wrth fesur tymheredd a monitro mewn ardaloedd peryglus, Ardaloedd pwysig, pwysau llestr mesur tymheredd arwyneb a monitro, large-scale and large-scale temperature measurement and monitoring, yn ogystal â mesur tymheredd a monitro yn y maes cludiant. Distributed fiber optic temperature measurement is widely used in temperature monitoring and fire alarm of facilities such as power, petrochemical, transportation, adeiladau, and water conservancy;
