Hotline-type gas sensor

Hotline gas sensors utilize a metal wire that heats up when electricity passes through it. As gas flows over the wire, it carries away heat, causing a change in resistance to detect gas concentration. They are commonly used for detecting combustible gas leaks and are widely applied in industrial safety monitoring and environmental protection testing.
Selection
When selecting, consider the compatibility between the types of gases to be detected and the sensors, ensure the operating temperature range covers the usage environment, the response speed meets monitoring requirements, long-term stability aligns with the usage cycle, and the protection rating is suitable for the installation location.
