Optical Accelerometer

FBG Accelerometer

FBG Accelerometer AL-01 transmits the acceleration change to the FBG after the FBG is properly packaged inside, and calculates the acceleration by measuring the wavelength shift of the fiber grating combined with the fast fiber grating interrogation technology. 


The AL-01 adopts the most advanced fiber grating sensing technology, small size, high sensitivity and high reliability, and can work in harsh environments for a long time. At the same time,the sensor can be designed into into two-axis and three-axis combinations through different structures. It is suitable for vibration monitoring of engines, generator pumps, bridges, roadbeds and other engineering structures.
