FS310 FBG Optical Long Gauge Sensor
Information >>>


The FBG Optical Long Gauge Sensor (FS310) is a fiber Bragg grating (FBG) based sensor with a durable, flexible polymer tube and stainless steel parts. The FS310 can be easily embedded into concrete or attached onto any structure to be monitored, and it offers great strain sensitivity and slight variation or movement of the structure to be monitored.
