Where to Buy Optical Vibration Sensors

The FBG-based accelerometer AL-01 transmits the acceleration 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 uses the most advanced fiber grating sensing technology, resulting in small size, high sensitivity and high reliability. It can work in harsh environments for a long time. The sensors can also be used in two-axis or three-axis combinations through different structures. They are suitable for vibration monitoring of engines, generator pumps, bridges, roadbeds and other engineering structures.

Fiber Bragg grating and micro Fabry–Pérot vibration sensors. From standard sensitivity to dramatically amplified or de-amplified sensitivity, from ultra-small to large industrial vibration sensor packaging, for environments from cryogenic to 800 °C, and with cores based on standard acrylate or polyimide coated fibers, or truly hermetic copper or gold coated fibers (T15, T25, T99, T130, T155, T160, T210-T290, and TFP10).

Based on the Fiber Bragg Grating (FBG) technology and the newLight optical sensor line, the FS65 accelerometer is a high precision vibration sensor tailored to measure acceleration at different frequencies from 0 to 50 Hz.

The accelerometer can be used in a large range of monitoring applications where low frequency, but relevant amplitude vibrations are present, including measuring load induced vibration of civil structures and ambient cable vibrations. The simultaneous measurement of vibration along different axes is possible using multiple accelerometers.
