Thermopile detectors T11361 series High-sensitivity thermopile detectors with thermistor For gas density measurements The T11361 series is a family of thermopile detectors equipped with an internal thermistor for compensating for output variations caused by changes in the ambient temperature. The T11361-01 is suited for gas density measurements or the like. It uses a TO-18 package with a window having high transmittance in the 3 to 5 μm spectral band. By attaching an external band-pass filter to the thermopile detector, customers can apply it to various types of gas density measurements. The T1136105 employs a 4.3 μm band-pass filter and is suitable for CO2 density measurements. Features Applications Spectral response: 3 to 5 μm (T11361-01), 4.3 μm (T11361-05) Gas density measurement and the like (T11361-01) TO-18 package CO2 density measurement (T11361-05) High sensitivity Built-in thermistor Absolute maximum ratings Parameter Symbol T11361-01 T11361-05 Operating temperature Topr -30 to +85 -10 to +80 Storage temperature Tstg -40 to +100 -20 to +85 Thermistor power dissipation Pth 0.2 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure product within the absolute maximum ratings.
