NX-IR4-Q

Quad-IR (IR4) Flame Detectors

  • Multi-Spectrum IR (IR4 : Quad-IR) Sensor Array
    • - detecting the invisible hydrogen flames as well as the typical hydrocarbon-based fires at increasingly longer distance
  • Slim-sized & Light-weight design
  • Increased detection coverage
    • - up to 80m or max.120°
  • Optical Path Monitoring without external reflector
    • - greatly reduces fault and maintenance where salt, heavy rain, sand or snow are constantly present
  • Approved to Safety Integrity Level 2 (SIL2-TUV)
  • Global Certifications
    • - ATEX / IECEx for hazardous areas
    • - FM3260 for performance
    • - SIL2(TUV) : IEC61508 for reliability
