IR7153是一样的5V电源,115mA电流,直径2.1mm,波长0-5um,高*,输出稳定,时间常数290ms,寿命在5V下40000小时用于气体分析The IR7153 is an incandescent lamp of size T-1, i.e. max. diameter 2.1 mm. It has beenspecified to be employed in gas detectors based on infrared (IR) absorption. The accessiblewavelength range amounts from the visible up to about 4.4 μm.The IR-source is especially well suited for the detection of carbon hydroxides at 3..3.5 μm andcarbon dioxide (CO2) at around 4.15...4.4 μm. For this application the modulation frequency canbe chosen up to 3 Hz. There is only a limited suitability of the source for the detection of carbonmonoxide (CO) around 4.6 μm, since for this band the gl* tran*ission is already decreasing.The cut-off wavelength is at 5 μm. 光谱 "
