Spectrex offers two versions of the new 40\/40 Series UV\/IR Flame Detectors:","Model 40\/40L (& LB) provides a combination of UV and IR sensors, where the IR sensor operates at a wavelength of 2.5-3.0 µm, and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires.","Model 40\/40L4 (& L4B) is identical to the 40\/40L except that the IR sensor works at a wavelength of 4.5 µm and is only suitable for hydrocarbon-based fires.","The UV\/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.","The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.","Features","Approvals
