Its fast speed of response (T50 < 3s) enables early leak detection, minimizing the risk of escalation. The 316 stainless steel construction ensures corrosion resistance in harsh offshore environments, reducing lifecycle costs.
Installation & Setup Guidance
Proper installation is critical for optimal performance. Mount the detector where gas accumulation is likely, and ensure the sensing element is unobstructed. The 4-20mA output can be configured as sink or source, simplifying integration with most control systems. For digital integration, use the optional Modbus RS485 via DX100(M) or HART® version 7. Always follow the manufacturer's wiring diagram and local electrical codes.
Maintenance & Reliability
Regular inspection is recommended to maintain accuracy. The detector's long-term stability is , with baseline drift ≤ ±2% FSD for methane (100% LEL range) over time. The IP66/67 rating allows for washdown cleaning without water ingress. Periodically verify the response using a certified calibration gas and the hand-held interrogator or HART® communications.
Compatibility & Integration
The 2108B2001N supports analog 4-20mA and optional digital outputs. It is compatible with Honeywell's DX100(M) for Modbus RS485 multidrop networks. HART® version 7 enables remote diagnostics and re-calibration. This flexibility allows seamless integration into existing safety systems.
Selection Guide & Purchasing Advice
When selecting a gas detector, consider the specific hydrocarbons present and the required measuring range (0-100% LEL). The Searchpoint Optima Plus offers a wide selection of hydrocarbon gas and vapor calibrations. For specialist applications, different measuring ranges and solvent calibrations are available.
