According to special requirements of vibration monitoring of large rotating machinery, such as Turbine and compressor, a non-contact fiber Bragg grating (FBG) based vibration detection sensor is designed. The magnetic coupling technology and elastic diaphragm are adopted to achieve the vibration detection by changing the axial strain of optical fiber grating. This paper describes the structure and working principle of the sensor, and studies the static and dynamic characteristics of the sensor… CONTINUE READING
