产品介绍
FBG Accelerometer
FBG Accelerometer 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 FBG Accelerometer 02 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 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.
Key Features
l High resolution and wide frequency response range
l High precision, high stability and reliability
l Small in size, waterproof and moisture-proof
l Fast, simple and repeatable installation
Applications
l Bridge cable force monitoring
l Vibration monitoring of various engineering structures such as bridges and roadbeds
l Frequency measurement of engines, generator pumps
