For some dangerous places with high or low oxygen content, we need to use oxygen alarm to monitor the oxygen concentration in the air in real time, so as to ensure the safety of operators. In order to ensure the accuracy of the measurement data, in the process of using the oxygen alarm, we must pay attention to the interference of operation or external factors on the detection data, so as to obtain accurate measurement data, so as to ensure the safety of production operations. Do you know how the accuracy of the oxygen alarm measurement data is affected? The following is a brief introduction by yi yun Tian:

The accuracy of oxygen alarm measurement data can be affected by the following factors:

1. Pollution of oxygen alarm:

When the oxygen alarm is reused, it is necessary to pay attention to whether air leaks when connecting the sampling pipeline, and the air leaked must be blown clean carefully, and a large amount of gas should not pass through the sensor as much as possible to extend the life of the sensor.In the process of pipeline system purification, in order to shorten the purification time, a certain method is needed. Riveting machines generally use high-pressure venting and small flow blowing alternately to quickly purify the pipeline.

2. Leakage self-test of oxygen alarm:

oxygen alarm must be strictly leak-checked before it is activated for the first time. The oxygen analyzer can only obtain correct data results under strict and leak-free conditions. Any connection points, solder joints, valves, etc. are not tight, will lead to the gas in the air into the pipeline and oxygen analyzer, resulting in inaccurate measurement data.

3. simplification and cleaning of gas path system:

microanalysis requires that various pipe fittings on the gas path must be effectively excluded, pollution of oxygen by dead ends in chamfering machine valves, headers, etc. Therefore, the manual pipe bender should simplify the gas path system as much as possible, and choose the connecting piece with small dead angle. And avoid the use of water seal, oil seal and wax seal and other equipment to prevent dissolved oxygen from escaping and causing pollution. It is also necessary to avoid adding purification equipment that is easy to cause pollution on the pipeline from oxygen to the inlet of oxygen alarm. Only in this way can we ensure that the gas path system of the oxygen alarm is clean and the data obtained is correct.

to sum up, we can see that the accuracy of the measurement data of the oxygen alarm will be affected by the pollution of the oxygen alarm, the leakage self-check of the oxygen alarm, the simplification and cleanliness of the gas circuit system and other factors. therefore, in order to ensure the accuracy of the measurement data of the oxygen alarm, we must pay attention to check these aspects before using the oxygen alarm.
