Abstract

The invention relates to a high-flow oxygen sensor. The high-flow oxygen sensor comprises a straight-through pipe, a control module and an ultrasonic probe; the ultrasonic probe is electrically connected with the control module; the ultrasonic probe is arranged on the straight-through pipe; the straight-through pipe comprises two channels, namely a first channel and a second channel, the first channel and the second channel are obliquely crossed and communicated with each other, and the diameter of the first channel is larger than that of the second channel; gas is transmitted by the first channel, ultrasonic waves transmitted by the second channel penetrate through the gas of the first channel, the real-time transmission time of the gas is obtained through different transmission speeds of the ultrasonic waves among the gases with different concentrations, and the gas concentration can be obtained through conversion from the real-time transmission time of the ultrasonic waves, and the flow of gas transmission can be calculated according to sound wave transmission time and oxygen concentration, so that the oxygen sensor can measure the oxygen concentration and the gas flow of the gas at the same time, the practicability of the oxygen sensor is improved, the cost of using large-flow oxygen sensor equipment is reduced, and the purchase price is also reduced.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a large-flow oxygen sensor. Background technique [0002] Existing oxygen generators and other equipment need to measure oxygen concentration and other indicators, and a series of electronic devices such as sensors need to be loaded to measure real-time indicators. [0003] Due to the insufficiency of the circuit and software, the existing gas flow sensor can only detect the gas concentration and flow at the same time, and needs to be used in conjunction with the oxygen concentration sensor, resulting in an increase in the cost of the equipment and an expensive price. Contents of the invention [0004] In order to overcome the current technical problem that the existing gas flow sensor can only detect gas concentration and flow at the same time due to the shortcomings of circuits and software, and needs to be used in conjunction with an oxygen concentration sensor, the present invention ...
