The 90° wide-angle field of view offers flexibility in positioning, though you must align the sensor to capture the most intense part of the flame's UV cone (typically the first third of the flame). Ensure the sight pipe remains clear of obstructions. For extreme heat applications, we recommend utilizing a cooling air purge through the sight pipe to maintain the sensor temperature below the +121°C limit.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the LG1093AA25 detect hydrogen flames?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
