Temperature compensation mountable strain sensors
Temperature compensation mountable fiber strain sensors OSST - 530 and OSST - 531 makes use of the sensitivity of fiber grating to measure the strain. Simultaneously, as temperature compensation, another FBG is used to monitor the temperature. The double FBGs are fixed inside a robust housing. The signals from the sensors are processed Fiber interrogation monitors.
