Fibre Bragg Grating

Fibre Bragg grating (FBG) pressure sensor has shown great potential in replacing the conventional electrical pressure sensor due to its adaptability to the harsh environment. However, increasing its resolution for low-pressure measurement is still a challenge. In this work, the bonding of FBG to a rubber-based diaphragm pressure transducer was proposed. The proposed pressure transducer had enhanced the sensitivity to 117.7 pm/kPa across the range of 40 kPa, which corresponded to the pressure resolution of 0.008 kPa. Furthermore, the proposed pressure transducer possessed a reference FBG for temperature compensation, where the overall temperature effect was less than 1%.

Fbg Sensors

Simple experiments for calibrating Fibre Bragg Grating (FBG) in order to measure strain and temperature have been successfully demonstrated in this study. This will allow convenient use of FBG sensor in the laboratory for measuring quantities. Linear curve fittings were employed for both the strain and temperature, and R2 values are determined respectively. The result showed a perfect correlation between FBG, strain and temperature. The approach can be employed with ease, simplicity in an inexpensive manner, in order harness the advantages offered by FBG sensors such as accuracy, precision, speed and high resolution.

In this paper, miniature air data system is designed based on thermally excited resonant silicon micro structural pressure sensor. The system employs thermally excited resonant silicon micro structural pressure sensor for the pressure measurement. Using miniature embedded computer, calculation of the parameters such as height, airspeed and mach number and real-time display by LCD are realized. The volume and weight of this system is only one-twelfth of the original. In addition, it has the characteristics of high accuracy, high resolution, high stability and repeatability.
