style="text-indent:25px">高效測(cè)溫光纖，提升您的生活質(zhì)量和工作效率。貴州管道測(cè)溫光纖特點(diǎn)</p><p style="text-indent:25px">感溫光纖，又名線型光纖感溫火災(zāi)探測(cè)器。用于溫度測(cè)量的一般為分布式光纖溫度傳感器，其主要運(yùn)用光纖的“光時(shí)域反射原理”以及“拉曼散射(Raman Scattering)溫度效應(yīng)”。當(dāng)一個(gè)光脈沖從光纖的一端射入光纖時(shí)，這個(gè)光脈沖會(huì)沿著光纖向前傳播。因光纖內(nèi)壁類似鏡面，故光脈沖在傳播中的每一點(diǎn)都會(huì)產(chǎn)生反射，反射之中有一小部分的拉曼散射光，其方向正好與入射光的方向相反。這種后向散射光的強(qiáng)度與光纖中的反射點(diǎn)的溫度有一定的關(guān)系。也就是說(shuō)，后向散射光的強(qiáng)度可以反映出反射點(diǎn)的溫度，利用這個(gè)現(xiàn)象，通過(guò)測(cè)量出后向散射光的強(qiáng)度，就可以計(jì)算出反射點(diǎn)的溫度，這就是利用光纖測(cè)量溫度的基本原理。另外，還可以根據(jù)后向散射光信號(hào)在光纖中的損耗來(lái)監(jiān)測(cè)光纖的故障點(diǎn)和斷點(diǎn)的位置，進(jìn)而獲知斷纖的有關(guān)信息。貴州管道測(cè)溫光纖特點(diǎn)</p></div>
