Stainless Steel High Precision Embedded Safety Fiber Bragg Grating
Application:
Fiber Brag Gratting is used for the long or short time encapsulated structure monitoring under harsh environment: embedded beam, column, pile foundation, support, retaining wall, hydraulic structure, lining, pier, base and foundation.
Introduction:
The Embedded FBG strain gauge is used to measure the strain changes inside concrete, it adopts a encapsulation structure to make the sensor itself and the concrete to achieve the stiffness matching which improve the embedding survival rate;
It's suitable for monitor the strain of long-time embedded beam, column, pile foundation, support, retaining wall, hydraulic structure, lining, pier, base and foundation.;for the temperature is compensated by embedding a strain-free cylinder.
Features:
●High precision, high stability, high reliability;
●Safe, anti-electromagnetic interference, corrosion resistance, pollution resistance, strong lightning resistance, can be used in strong electromagnetic interference, high lightning strike, flammable, easy explosion and other harsh conditions;
● Distance for transmission signal up to 40Km;
● Distributed measurement, multiple sensors connected on a single optical fiber (typical: 12)
● Simple layout, can be use together with other types of fiber grating sensor;
