Brief Introduction to Fixed Gas Detectors
This is a commonly used detector in industrial equipment and production processes. It can be installed at specific detection points to detect specific gas leaks. Yiyang fixed detectors are generally two-piece, with a detection head composed of sensors and transmitters installed as a whole on the detection site, and a secondary instrument composed of circuits, power supplies, and display alarm devices installed as a whole in a safe place for easy monitoring. Its detection principle is as described in the previous section, but it is more suitable for the continuous and long-term stability required for fixed detection in terms of process and technology. They also need to be selected based on the type and concentration of the gas on site, and attention should be paid to installing them in the most likely leak location of specific gases, such as selecting the most
effective height for sensor installation based on the specific gravity of the gas, and so on.
Introduction to basic information about gas detectors
Gas detector is an instrument tool for detecting gas leakage concentration, including portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc. Mainly using gas sensors to detect the types of gases present in the environment, gas sensors are sensors used to detect the composition and content of gases.
It is generally believed that the definition of gas sensors is based on the classification of detection targets, which means that any sensor used to detect gas composition and concentration is called a gas sensor, regardless of whether it uses physical or chemical methods. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use generally consistent detection principles.
