Application Scenarios

Oil & Gas Production: Deploy the 2108N4000N alongside Honeywell 2108B2001 Searchpoint Optima Plus for comprehensive wellhead and separator monitoring, ensuring early leak detection before concentrations reach dangerous levels.

Petrochemical Processing: Integrate with Honeywell 2108B2003N Analytics Optima Plus to create multi-point detection networks around process units, distillation columns, and storage tank farms.

Offshore Platforms: The rugged IP66/67 construction withstands harsh marine environments, working seamlessly with flame detection systems like Det-Tronics X3301A4M13T2 Multispectrum IR Flame Detector for comprehensive safety coverage.

Refineries & Tank Farms: Position detectors at loading racks, pump stations, and vapor recovery units, complementing catalytic sensors such as Honeywell 05701-A-0284 Catalytic Sensor Drive Module for dual-technology protection.

Integrated Safety Solutions

The 2108N4000N forms the cornerstone of comprehensive gas detection architectures. When paired with Honeywell LG1093AC01 Flame Detector, facilities achieve both gas leak detection and fire protection in a unified safety system. For UV flame sensing applications, combine with Honeywell 261A1812P012 UV Flame Sensor to detect both hydrocarbon releases and ignition events.

Protection modules like the Honeywell 04230-A-1025 SHC Protection Device Module enhance system reliability through advanced diagnostics and fail-safe operation, ensuring continuous monitoring even during maintenance cycles.

Key Advantages

Immune to Sensor Poisoning: Unlike catalytic sensors, infrared technology remains unaffected by silicones, sulfur compounds, and halogenated hydrocarbons
Zero Oxygen Dependency: Operates reliably in oxygen-deficient atmospheres where catalytic detectors fail
Extended Calibration Intervals: Stable optical design reduces maintenance frequency and lifecycle costs
Fail-Safe Architecture: Self-diagnostics with automatic fault reporting ensure continuous protection
Harsh Environment Performance: Functions across extreme temperature ranges from Arctic to desert conditions

Common Questions & Answers

Q: What gases can the 2108N4000N detect?
A: This infrared detector responds to all hydrocarbon gases including methane, ethane, propane, butane, pentane, hexane, and heavier alkanes. It’s optimized for methane (natural gas) but cross-calibrated for other hydrocarbons.

Q: How does this compare to catalytic bead sensors?
A: Infrared sensors offer superior immunity to poisoning, no oxygen requirement, longer calibration intervals (typically 12-18 months vs. 6 months), and better performance in inert atmospheres. The 2108N4000N is ideal for applications where catalytic sensors experience shortened lifespan.

Q: Can I integrate this with existing control systems?
A: Yes, the standard 4-20 mA output integrates seamlessly with DCS, PLC, and SCADA systems. The detector also supports HART protocol for advanced diagnostics and remote configuration.

Q: What maintenance does the detector require?
A: Routine maintenance includes quarterly functional testing, semi-annual optical window cleaning, and annual calibration verification. The infrared sensor element typically lasts 5+ years without replacement.

Q: Is the detector suitable for hydrogen applications?
A: No, infrared technology detects hydrocarbon gases specifically. For hydrogen detection, consider electrochemical or thermal conductivity sensors designed for H2 monitoring.

Q: What certifications does the 2108N4000N hold?
A: The detector carries ATEX Zone 1, IECEx, CSA Class I Division 1, and is SIL 2 capable per IEC 61508, making it suitable for global hazardous area installations.
