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
- 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 : (pending)
- - SIL2(TUV) : IEC61508 for reliability
- Spectrum Response : Four IR Bands
