The principle of infrared spectroscopy absorption technology (also known as laser technology) is that SF6, as a greenhouse gas,SF6 Gas Purity Analyzerhas a strong absorption characteristic for specific bands of infrared light. The characteristics of infrared spectroscopy technology are high cost, complex structure, high sensitivity, and it is not easily affected by environmental clutter or power frequency interference signals, but it is also easily affected by environmental dust and humidity. Over time, the detection errors caused by changes in environmental temperature and humidity are large. Due to its principle of actively extracting gas from the test point, the effect is early leak detection and rapid response. At the same time, the system structure also brings great convenience to the wiring in engineering implementation.
During the development process, the complex structure of infrared spectroscopy technology has brought great difficulties to development, because the design involves optical content, and the difficulties in processing technology have caused a sharp rise in cost. However, the advantages of infrared spectroscopy technology are reflected in online systems. Its fast response speed and high sensitivity can meet long-term work in better environments such as dry conditions, but the internal photoelectric emission and receiving components are easily affected by the environment, so it is recommended to replace the internal sensors or return them to the manufacturer for inspection every two to three years.
