GFRP-packaged FBG strain sensor

Product Description

一、Introduction CB-FBG-EGE***0 high-durable enlarge-ended GFRP-packaged FBG strain sensor is national significant new product (serial number: ***4ED******0), which was developed based on the patent of invention“FRP-OFBG intelligent composite bar”。Tthe non- rubber seal technology is adopted to overcome the durable question which is the puzzle of the traditional FBG sensors sealed by rubber. It can deform together with concrete by the enlarged end. This product has many merits such as installation simpleness 、knock-down、wide range、high-durability、high accuracy etc. 二、Main indexes The main indexes of CB-FBG-EGE***0 at *0℃ as follow： Performance Index Range ± ***0με Accuracy (2～3με)（by integrator） Gauge *0cm、*0cm、**0cm（custom-built） Resolution 1με (by integrator) Strain sensitivity 1.*5~1.*5 pm/με（confirm by calibration） Repetition(NIM test) <0.5％ Linearity(NIM test) <0.8％ Lagging(NIM test) <0.5％ Wavelength of FBG ***0nm～***0nm Young’s modulus about *0GPa Reflectance ratio ≥ *0% Installation way embedding directly Pigtail: steel armoured fiber optic cable(one or double is alternative ) Durability >*0years 三、Main applications CB-FBG-EGE***0 high-durable enlarge-ended GFRP-packaged FBG strain sensor can be applied to monitor strain of concrete interior, also be applied in structural construction、completion test and secular health monitoring of civil engineering such as bridges、buildings、hydro-structures etc.
