FBG Pressure Sensors Application

Fiber Bragg grating (FBG) pressure sensors perform spectral analysis of the reflected wavelength to measure different parameters. The basic principle is that different factors applied on the fiber optic pressure sensor affect the Bragg wavelengths; modified physical or geometrical properties of the FBG are indirectly measured in that case. FBG pressure sensor measures the relative pressure and level of liquids and gases in different containers and pipelines. It can be used, as well, for indirect control of the flow and the level of liquid in tanks and pipes.

The biggest issue for FBG pressure sensors is to differentiate between strain and temperature changes, and to precisely measure pressure. When the temperature changes a lot, it becomes challenging to make correct pressure measurements. There are two ways to approach this problem, one of them is to make a sophisticated athermal coating and another one is to implement a temperature compensation strategy.

FBG pressure sensors have the highest accuracy and stability. They are small and portable, immune to electromagnetic interference and they can measure high speed events. FBG pressure sensor measurement is an essential technology in many industrial applications such as liquid level monitoring in oil storage tank, down-hole pressure measurement, gas turbine engine and other fields.
