Abstract

The invention discloses a sensor which is used for measuring the gas of elementary substance and the compound gas. The sensor comprises an air chamber, an infrared transmitter, an infrared receiver, a reflector, an air inlet and an air outlet. The infrared transmitter is arranged at the position of the air inlet on the inner wall of the air chamber; the infrared receiver is arranged at the position of the air outlet on the inner wall of the air chamber; the inner wall of the air chamber with the infrared transmitter is provided with a reflector array I; the inner wall of the air chamber with the infrared receiver is provided with a reflector array II; the inner wall of the air chamber without the reflector array is uniformly coated with the substance which is used for absorbing the useless light or preventing the air chamber from absorbing the infrared light. The sensor has the advantages of simple structure, low costs, accurate measurement results, and reliable work.

Description

technical field [0001] The invention relates to the field of sensors, in particular to the field of sensors for measuring gas. Background technique [0002] With the development of social economy, in the production process of various large-scale industrial enterprises (such as: coal mines, petroleum, air separation, etc.), certain production links need to monitor the gases (such as: NO X , O 2 , CO, CO 2 and other gases) for testing to maintain normal production needs. The principle of gas detection is to use the Lambert-Beer theorem to detect signals through the different absorption of different gases by absorbing substances, but the internal design of existing detectors is complex, bulky and expensive. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a sensor for measuring elemental and compound gases with simple structure, low cost and accurate measurement. [0004] The present invention is achieved like this...
