Troubleshooting and Application Introduction of Carbon Dioxide Detector
The carbon dioxide detector detects carbon dioxide gas in the field environment through the absorption principle of infrared light source. Working principle The infrared detector uses the principle of infrared light source absorption to detect flammable hydrocarbon gases in the field environment.
The CO2 detector uses a tiny plug-in optical detector built into a stainless steel housing. The gas to be detected diffuses and enters the optical cell through this sintered stainless steel flame arrester.
A lamp in the gas chamber provides a circulating infrared light source which is reflected in the gas chamber and terminated at two pyroelectric sensing chips. One is the "active sensor" and the other is the "reference sensor". Each pyroelectric sensing chip outputs a level respectively, and the carbon dioxide concentration can be calculated by the ratio of the output levels of the two sensing chips.
Troubleshooting methods for the cause of carbon dioxide detector failure:
1. Insufficient working hours.
2. Insufficient charging or the battery has reached the end of its service life. Check the charging stand to make sure the contacts of the charging stand are in good contact, or replace the battery. During maintenance, the model, specification and parameters of the components in the original circuit shall not be changed, and the original package shall not be changed. All repairs must be performed on well by professionals. If the user cannot repair it, it can be returned to the factory for repair or replacement.
3. Alarm silent, poor contact, or circuit failure. Check solder joints, wires and circuits.
4. The digital tube is missing or not bright. The digital tube is broken or the welding is loose. Replace the nixie tube or repair welding. The measurement error of the carbon dioxide detector is too large: 1. It is in an environment containing CO2 gas when it is turned on or zeroed. 2. The battery of the alarm device is insufficient. 3. The alarm device drifts.
In the actual application process of the carbon dioxide detector, there will always be one or another common scope. Today we will summarize for you the analysis of the related application of my carbon dioxide detector. One thing that is well known is that detectors are widely used in the process of extensive air quality monitoring.
In the aspect of environmental monitoring, the carbon dioxide detector can continuously detect the content of carbon dioxide in large-scale production sites in real time, so that it can dynamically carry out effective early warning and prevention of some dangerous accidents that have not yet appeared. In addition, in the environment In the field of quality control, we should fully apply it to carbon dioxide detectors.
Because such a machine can fully display the overall quality of the environment during the dynamic detection process. In this way, effective values are provided for the formulation of measures such as environmental control and adjustment testing.
A large number of carbon dioxide detectors have introduced various ozone detectors and combustible gas detectors, providing a large number of products and services for users in various industries. Gongcai.com has close cooperative relations with many famous professional manufacturers in the world. At the same time, the company makes full use of the advantages of the international Internet, not only can provide users with a wide range of product selection opportunities, obtain excellent cost performance, but also quickly provide users with scientific and technological information.
