Abstract

The invention relates to a calibration method for an oxygen sensor of high-pressure nitrogen production equipment. The calibration method comprises the following steps: preparing clean air from the high-pressure nitrogen production equipment; carrying out pressure regulation and flow control on the clean air, and then introducing the clean air into the oxygen sensor; and enabling the oxygen sensor to upload an analog signal to a control module to complete calibration. The clean air in the high-pressure nitrogen generation equipment is used as the calibration gas of the oxygen sensor, additional calibration gas is not needed, the calibration process is simple and easy to implement, the time cost is saved, and normal use of the nitrogen generation equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of oxygen sensors, in particular to an oxygen sensor calibration method for high-pressure nitrogen equipment. Background technique [0002] Oxygen sensors are used to detect oxygen content in various environments. With the gradual maturity of detection technology, they are widely used in technical fields such as cultural relics, automobiles, chemicals, and mechanical equipment. [0003] As the oxygen sensor is used over time, its detection accuracy will gradually decrease. Therefore, it is necessary to perform a calibration once the oxygen sensor has been working for a period of time. The traditional calibration method is to use the standard oxygen content gas to detect the slope calibration, and the oxygen sensor needs to be disassembled before the calibration, which is cumbersome to operate and difficult to put into actual production. Contents of the invention [0004] Aiming at the technical problems ...
