Definitions
- the present invention relates to a hydrogen gas concentration sensor and a hydrogen gas concentration measuring apparatus for measuring a hydrogen gas concentration.
- the hydrogen gas concentration sensor and the hydrogen gas concentration measuring apparatus provide a hydrogen gas concentration sensor and a hydrogen gas concentration measuring apparatus that can maintain high measurement accuracy in a wide measurement range by photocatalysis. be able to.
- FIG. 1 is a plan view showing a schematic configuration of a hydrogen gas concentration sensor according to an embodiment of the present invention
- FIG. 2 is a cross-sectional view showing a schematic configuration of the hydrogen gas concentration sensor.
- the hydrogen gas concentration measuring device 20 Since the hydrogen gas concentration is detected as described above, as shown by the solid line in FIG. 7, the hydrogen gas concentration measuring device 20 has a value of 0 to approximately 0.2 in the hydrogen gas measurement range of 0 to 1. The range is measured with the first hydrogen detection film 12a having the highest measurement sensitivity, the range of about 0.25 to 0.5 is measured with the second hydrogen detection film 12b, and the range of about 0.5 to 1 is the highest. Measure with the third hydrogen sensing film 12c, which has a wide measuring range.
- the hydrogen gas concentration measuring device 20 processes the resistance value measurement results of the thin film layers 13a to 13c with the same resolution, that is, for example, analog-to-digital conversion with 10 bits, measurement at a low concentration is possible. Accuracy can be improved and high measurement accuracy can be maintained over a wide measurement range.
