Tungsten Filament Lamps

Gilway's T-3/4 and T-1 tungste n filament lamps have been optimised for their near and mid-range infrared output. The lamps are used as infrared sources in gas sensors, typically sensors of carbon monoxide, hydrocarbons, and hydrosulfates. Features include compact, double coiled tungsten filaments resulting in rugged construction and small size approximating a point source. Thin envelope walls of 0.1 mm provide minimum infrared attenuation. Smaller than a grain of wheat, lamp 4115 measures 2.3 mm in diameter and operates on 5.0 V at 115 mA. Types 1150 and 1088 measure 3.0 mm in diameter with a design voltage of 5.0 at 115 mA and 140 niA, respectively. Lamps are longlife with ratings of 18,000 to 40,000 hours at the design voltage.
