A robust fiber Bragg grating (FBG) hydrogen gas sensor for reliable multipoint-leakage monitoring has been developed.
The sensing mechanism is based on shifts of center wavelength of the reflection spectra due to temperature change caused by catalytic combustion heat.
The sensitive film which consists of platinum-supported silica (Pt/SiO2) catalyst film was obtained using sol-gel method.
The precursor solution was composed of hexachloroplatinic acid and commercially available silica precursor solution.
The atom ratio of Si : Pt was fixed at 13 : 1.
A small amount of this solution was dropped on the substrate and dried at room temperature.
After that, the film was calcined at 500°C in air.
These procedures were repeated and therefore thick hydrogen-sensitive films were obtained.
The catalytic film obtained by 20-time coating on quartz glass substrate showed a temperature change 75 K upon exposure to 3 vol.% H2.
For realizing robust sensor device, this catalytic film was deposited and FBG portion was directly fixed on titanium substrate.
The sensor device showed good performances enough to detect hydrogen gas in the concentration range below lower explosion limit at room temperature.
The enhancement of the sensitivity was attributed to not only catalytic combustion heat but also related thermal strain.
