IR1 Series Single Gas Sensors

SGX Sensortec's infrared single gas sensor for hazardous environments

SGX Sensortec's infrared sensors use the proven non-dispersive infrared (NDIR) principle to detect and monitor the presence of gases. With an infrared source and specific filtering on the pyroelectric detectors mounted inside the optical/gas cavity, individual gases or types of gas can be identified and their concentrations determined. These sensors are suitable for reliable monitoring of gas levels in general safety applications where the sensor size is restricted and require a flameproof enclosure for hazardous environments.

  • For detection of the following gases:
    • Carbon dioxide (IR11 series)
    • Hydrocarbons (IR12 series, IR13 series)
    • Acetylene (IR14 series)
  • Gas concentration ranges:
    • 0 to 5% carbon dioxide (also suitable for 0 to 0.5% v/v)
    • 0 to 100% carbon dioxide (also suitable for 0 to 10%)
    • 0 to 100% v/v hydrocarbons (also suitable for 0 to 100% LEL)
    • 0 to 100% v/v acetylene (also suitable for 0 to 100% LEL)
