Quasar 900 infrared open path gas detection (SafEye)

Capable of replacing many point gas detectors, the SafEye Quasar 900 open path infrared gas detector is an innovative and relevant solution for the detection of flammable hydrocarbons in industry. It consists of a Xenon flash infrared emitter and an infrared receiver that can be split up to 200 meters away.

  • Open path for combustible hydrocarbon types C1 to C8 (methane, ethylene, propane, alkanes, alkenes, naphthenes, benzenes) detection
  • Detection range from 7 to 200 meters in 4 different models (same detector, various sources)
  • Detection in the harshest weather conditions thanks to heated optics
  • 4-20mA, RS485 Modbus and HART outputs and status LED
  • ATEX, IECEx, CSA, FM, UL, SIL2 (IEC61508) approval
Additional information

The Quasar 900 SafEye open path infrared gas detector identifies the presence of combustible hydrocarbons by analyzing atmospheric absorption and comparing it to a non gas affected area. It uses a xenon light source associated with an integrated electronic module to provide a high-performance gas monitoring system with a short response time (T90 less than 3 seconds).

The SafEye Quasar 900 infrared open path can replace up to 20 fixed explosive gas detectors (explosimeters) in various applications, reducing installation and maintenance costs. It is particularly suitable for harsh industrial environments where dust, fog, rain, snow, or vibration can cause a severe signal reduction.

This open path infrared gas detection offers many significant technical advantages, like larger monitoring areas and less strategic placement of gas detectors in the monitoring area. Certified ATEX, IECEx, CSA, FM, UL, SIL2, it is particularly suitable for many industrial applications or classified sites such as offshore platforms, ships, chemical and petrochemical plants, gas and oil pipelines but also large-scale storage areas, and CNG bus and truck maintenance centers.

Main hydrocarbons detected: Acetylene (C2H2) - Benzene (C6H6) - Butane (C4H10) - Ethylene (C2H4) - Isobutylene (C4H8) - Methane (CH4) - Pentane (C5H12) - Propane (C3H8) - Styrene (C8H8) - Toluene (C7H8)
