定點(diǎn)式應(yīng)變傳感光纜
Point Style Strain Sensing Cable
產(chǎn)品描述Description
定點(diǎn)式應(yīng)變傳感光纜是一種專(zhuān)業(yè)BOTDR和BOTDA原理研究的一種應(yīng)力、應(yīng)變傳感光纜，光纜由中心的緊包型應(yīng)變傳感光纖+鎧裝保護(hù)層+熱塑性外護(hù)套組成。光纖與鎧裝層處于自由活動(dòng)狀態(tài),再通過(guò)一定間距對(duì)應(yīng)力傳感光纖與鎧裝層和外護(hù)套進(jìn)行固定,從而實(shí)現(xiàn)空間非連續(xù)非均勻的分段,應(yīng)變測(cè)量結(jié)果可直接進(jìn)行位移量的計(jì)算
Fixed-point strain sensing optical cable is a kind of stress and strain sensing optical cable which designed for BOTDR and BOTDA sensing system. The optical cable is composed of the compact strain sensing optical fiber in the center, armored protective layer and thermoplastic outer sheath. T The optical fibers are interactively fixed in the armored tube by a certain distance, which device the cable to several distances to monitor.
產(chǎn)品特點(diǎn)Features：
通過(guò)間隔地固定光纖以實(shí)現(xiàn)光纜的分區(qū)測(cè)量；To divide the cable to several detective distance through the interval fixed partition of fiber
分區(qū)點(diǎn)可見(jiàn)，便于固定安裝；The fixed point is easy to install.
應(yīng)變光纖可以選用不同類(lèi)型的光纖；The strain sensing fiber can be chosen
應(yīng)變光纖被鎧裝鋼管保護(hù)，可適合各種惡劣環(huán)境The fiber is protected by the armored tube, which make the cable suitable for various application environment.
