Working principle and application of online gas detector
Online gas analyzer is an instrument used to analyze the composition of gases, and it belongs to a type of process analysis instrument. Gas analyzer is a chemical parameter measuring instrument. In many industrial production processes, the status of gas analysis instruments is on par with physical parameter measuring instruments such as pressure instruments and flow meters. It can play an important role in controlling the production environment and reducing safety accidents.
Online gas analysis instrument is a tool used for gas composition analysis and testing, which can obtain data on certain types and contents of components. However, gas analysis instruments are not simple tools. They are not as structurally simple as flow meters and pressure gauges, nor are they as easy to operate and use as various thermal instruments. It is a type of tool with complex structure and high technical difficulty in use. Using gas analysis instruments is a specialized technique that is complex and difficult to master.
Generally speaking, the application of online gas analysis instruments is a unique technical work, and it is a research-oriented work. However, this is not recognized and understood by outsiders. Online gas analyzer is used for continuous analysis of the content of a gas such as CO, CO2, SO2, CH4, NH3, etc. in multiple gas mixtures.
The difference between gas alarm and gas detector
Gas alarm is an automatic alarm that sounds when toxic or similar gases are detected, similar to an automatic fire extinguisher. There is a detection module in the alarm. When the gas concentration reaches a certain limit, also known as the explosion limit, the alarm will sound to remind people to take measures. Gas detectors can detect various gas concentrations. Often used in places with gas leaks such as chemical plants, oil and gas stations, steel plants, etc. Widely used.
How to distinguish between gas alarm and gas detector in terms of structure? In short, it is the distinction between fixed and portable. Gas alarm and gas detector are distinguished from each other in terms of structure. Both are gas detection equipment, and there are two product terms for gas detection equipment: gas alarm and gas detector. If we want to distinguish between them, we can use the following two terms:
Gas detector: A gas detector is a device where people actively detect gases in the environment to see what harmful substances are present. Gas detector is an instrument tool for detecting gas leakage concentration, mainly referring to portable/handheld gas detectors. Mainly using gas sensors to detect the types of gases present in the environment.
