Flame infrared sensor REG-X1214H

The working principle of infrared photo-conductive sensor is based on the photo-conductive effect of semiconductor materials, converting the change of infrared radiation energy into the change of resistance. This type of sensor has strong absorption and response in the near and middle infrared (1.0~5.0um) spectral bands. After integrating the semiconductor cooling chip TEC, it can realize stable control of the internal temperature of the sensor, reduce environmental interference and improve responsiveness; Refrigerated infrared photo-conductive sensor can be used in the field of low concentration infrared gas detection (13CO2, NH3, etc.) and spectral analysis filed. Application 13CO2 breath analyzer; Carbon emission gas detection; Infrared spectrum analysis; Features High detection rate; Fast response; TO-8 package; Stable refrigeration; Customizable window Specifications Table 1: Technical indicators (sensitive chips) Item - Typical - Unit Photosensitive area - 2*2 - mm Response wavelength range - 1~5 - um Peak wavelength - 3.8 - um Response Time - 20 - us Peak responsivity - 4*104 - V/W Peak Normalized Detection Rate - 1*1010 - cm·Hz½/W Dark resistance - 0.5~5 - MΩ Operating temperature - -30~70 - ℃ Table 2: Technical indicators (TEC/NTC) Performance index - Typical - Unit TEC - Refrigeration level - Level 2 - / Maximum voltage - 6.1 - V Maximum current - 1.4 - A NTC - Resistance - 10k±1%Ω B-value constant - 3435±1% - K
