Title:
ANNULAR MULTI-POINT REFLECTIVE PHOTOELECTRIC GAS SENSOR PROBE
Document Type and Number:
WIPO Patent Application WO/2019/228407
Kind Code:
A1
Abstract:
An annular multi-point reflective photoelectric gas sensor probe, comprising an annular multi-point light reflection ring. The annular multi-point light reflection ring is a hollow cylinder structure, and upper and lower side surfaces of the hollow cylinder structure are each provided with a cover plate. A cavity formed by the hollow cylinder structure and the cover plates thereof is a gas absorption tank that accommodates a gas to be tested, wherein the center of one of the cover plates is provided with a solid cylinder that reduces the total volume of the gas absorption tank. The hollow cylinder structure is provided thereon with a light beam entrance and exit opening, and a parallel light transceiving module is fixedly disposed at the opening. The parallel light transceiving module is used to generate parallel light and transmit the processed parallel light to the gas absorption tank for outputting after a plurality of reflections. The present design for annular multi-point reflection not only reduces the volume of an absorption tank of a sensor probe but also increases the optical path, while simultaneously also greatly improving the stability and reliability of the optical path, and lessens production and processing costs while reducing the difficulty of debugging.
