Application areas of gas detectors
Carbon dioxide is the main culprit of greenhouse effects. Not only that, where people live, the concentration of carbon dioxide is too high, which directly affects people's health, so the birth of carbon dioxide detectors is indispensable. Application scope of carbon dioxide detector: It is suitable for detecting CO2 concentration in industrial, agricultural and residential environments. Today I will introduce two carbon dioxide detectors and their applications in different fields for everyone to learn.
1. Fixed gas detector:
This is a detector commonly used in industrial equipment and production processes. It can be installed at specific detection points to detect specific gas leaks. Fixed detectors are generally two-piece. The detection head composed of sensors and transmitters is installed as a whole at the detection site. The secondary instrument composed of circuits, power supplies and display alarm devices is installed as a whole in a safe place for easy monitoring. Its detection principle is the same as that described in the previous section, but its process and technology are more suitable for the continuous and long-term stability required for fixed detection. They should also be selected according to the type and concentration of the gas on site. At the same time, attention should be paid to installing them in the parts where specific gases are most likely to leak. For example, the most effective height for sensor installation should be selected based on the specific gravity of the gas, etc.
2. Portable gas detector: Because the portable instrument is easy to operate and small in size, it can be carried to different production areas. The electrochemical detector is powered by alkaline batteries and can be used continuously for 1,000 hours; composite instruments use rechargeable batteries (some have Using memoryless nickel-metal hydride or lithium-ion batteries), they can generally work continuously for nearly 12 hours. Therefore, such instruments are increasingly used in various factories and health departments.
Manufacturers of energy-saving and environmentally friendly products: Let’s take manufacturers of energy-saving doors and windows as an example: Nowadays, there are many energy-saving doors and windows that can be ventilated without opening the windows. In order to prove the energy-saving and ventilation properties of the products, manufacturers install energy-saving doors and windows. Give customers a carbon dioxide and temperature monitor so that they can measure indoor carbon dioxide concentration at any time. This machine can also monitor indoor temperature and ventilation rate at the same time. With these data that can be scientifically monitored at any time, these customers feel that after using energy-saving doors and windows You will also feel more at ease.
Underground production: A lot of toxic gases and carbon dioxide will be produced during underground operations. Too high a concentration of carbon dioxide will cause people to be severely hypoxic underground, making them unable to breathe and unable to work normally. Placing a carbon dioxide detector in the underground working environment can monitor the concentration of carbon dioxide at any time. Whether it is within the normal working range, and at the same time, the underground temperature can be monitored, so as to avoid some accidents and carry out relevant protection work.
Kindergartens, offices, schools, supermarkets: For example, there are dozens or hundreds of students in school classrooms. If the windows are not opened for a long time, the carbon dioxide concentration will increase, causing teachers and students to feel dizzy or sleepy. , reduce learning efficiency. If there is a carbon dioxide monitor in each classroom, adjust the machine to a suitable alarm value. If the alarm occurs, you can open the window to get fresh air. This will not only ensure the quality of the air, but also allow the students to have a quiet time. A learning environment free from outside interference. In crowded public places, such as supermarkets and stations, long-term operation of air conditioners also leads to a waste of resources. Placing carbon dioxide and temperature monitors can monitor the carbon dioxide concentration and indoor temperature in these public places at any time, and adjust the ventilation rate and temperature as needed, which will save a lot of resources and expenses.
