Operating Principle
  • TDLAS (tunable diode laser absorption spectroscopy) for methane - laser-based, immune to poisoning, no oxygen required
  • Catalytic combustion for methanol - proven technology for combustible gas in the LEL range
  • Infrared (NDIR) for carbon dioxide - stable, selective, unaffected by oxygen deficiency
  • Electrochemical cells for oxygen, hydrogen sulfide, ammonia and chlorine - oxygen measured as volume percent, toxic gases at ppm-level sensitivity
Performance Features
  • Wide detection range - broad gas-type coverage with accurate measurement
  • Customised gas hoods - compatible with waterproof covers, calibration covers and accessories
  • Full-colour LCD display - improved environmental visibility and dark-environment operation
  • Rugged design - explosion-proof, anti-static, anti-EMI, suitable for complex field environments
  • Flexible connectivity - supports 4-20 mA, RS485, wireless and other transmission modes
  • Scalable architecture - works with controllers for multi-point centralised management
Sensor Technology and Long-Term Stability
The methane variant GT-C100 uses TDLAS, a laser absorption method that requires no oxygen and is not poisoned by silicones or sulfur compounds, making it ideal for cargo and fuel-gas service. The methanol variant uses catalytic combustion for combustible gas in the LEL range, while oxygen is measured by an electrochemical cell across 0-25% volume range. Infrared measurement of carbon dioxide remains selective even with fluctuating oxygen levels, while electrochemical cells for hydrogen sulfide, ammonia and chlorine provide ppm-level sensitivity. Accuracy is ±3% FS on LEL, infrared and oxygen models, ±2% FS on ammonia and ±5% FS on hydrogen sulfide and chlorine.
Interfaces & System Integration
Concentration data is transmitted via 4-20 mA, RS485 or wireless to the AIRPPB Gas Alarm Control Cabinet, which can supervise up to 112 field detectors. The central cabinet supplies power, performs processing, raises alarms and drives fire-protection linkage.
Typical Applications
Location Why it matters
Double-wall ventilation ducts Confined space with limited ventilation - leak accumulation is high-risk
Fuel-tank joints & connections Primary leak point on fuel handling systems
Fuel preparation rooms Hot-work adjacent zone with continuous fuel handling
Engine rooms & pump rooms Equipment density and high-temperature surfaces
LNG cargo areas Cryogenic flammable-gas risk
Certifications & Approvals

  • BV Type Approval Certificate (Bureau Veritas) - Certificate No. 81499/A0 BV
  • LR Type Approval Certificate (Lloyd's Register)
  • SIL3 Functional Safety Certification
  • Explosion-Proof Conformity Certificate
  • CCS Cyber Security Certificate
