BOTDA鎧裝感溫光纜
BOTDA Armored Temperature Sensor Cable
產品描述
BOTDA鎧裝感溫光纜是一種基于布里淵散射原理光纖傳感系統的溫度補償光纜。光纜由PBT松套管或無縫鋼管、鎧裝編織層、芳綸加強層以及LSZH外護套組成。光纖在松套管里有一定的余長，在光纜正常的應力范圍內不會產生應變反應。產品可以用于布里淵系統的溫度補償光纜或基于布里淵系統的測溫光纜。
BOTDA armored temperature sensing cable is a temperature compensation cable based on Brillouin scattering principle. The cable is composed of PBT loose tube or seamless steel tube, armored braid layer, aramid yarn reinforcement layer and LSZH outer sheath. The fiber has a certain excess length in the loose tube, which will not strain response within the normal stress range of the cable. The product can be used for brillouin system temperature compensation cable or DTS sensor cable.
產品特點
松套管結構，精確控制余長 Loose tube structure, excess length is controlled.
拉力范圍內應力不敏感 Strain is not sensitive in the normal range of tensile strains.
該光纜防鼠,防蟻 Anti mouse bite, anti ants bite.
推薦應用
