Title:
GAS SENSOR PROBE HAVING MULTIPOINT REFLECTION RECTANGULAR ABSORPTION CELL, AND DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/134518
Kind Code:
A1
Abstract:
A gas sensor probe having a multipoint reflection rectangular absorption cell, and a detection device. The probe comprises: an upper cover plate (1), the surface of the upper cover plate (1) being provided with gas diffusion holes (11), and a metal filtering screen (12) being provided above the gas diffusion holes (11); a lower cover plate (2) located under the upper cover plate (1) and detachably connected to the upper cover plate (1), a circuit through hole being formed in the bottom of the lower cover plate (2); a light path module (3) located in an internal space defined by the upper cover plate (1) and the lower cover plate (2) and used for collecting a detection signal; and an electronic processing circuit board (4) located in the internal space defined by the upper cover plate (1) and the lower cover plate (2), located below the light path module (3), electrically connected to the light path module (3), and used for adjusting the light path module (3). The probe is simple in structure, convenient to mount and manufacture, and low in cost, and by designing a measuring light path to be of a two-dimensional distribution structure, the volume of the absorption cell is reduced, the structural stability of the light path is improved, and high detection precision is achieved at the same time.
