Description

Honeywell 2108B2001N Point-type Infrared Gas Detector

Product Dimensions：

The Honeywell 2108B2001N is a high-performance Searchline Excel Receiver, a critical component of the Searchline Excel Open Path Gas Detection (OPGD) system. It is designed to work in tandem with a Short-Range (SR) Transmitter to detect flammable Hydrocarbon gases over a specific distance.

Product Detailed Description

The 2108B2001N is the Short-Range Receiver unit, specifically calibrated for distances between 5 and 40 meters. It operates on the principle of infrared (IR) absorption. As a gas cloud passes between the Transmitter and this Receiver, the unit measures the change in IR intensity to determine the gas concentration (measured in LEL.m).

Technical Parameters

Product Advantages

• Immunity to False Alarms: The dual-wavelength IR technology is highly resistant to interference from sunlight, fog, rain, or vibration, ensuring high reliability in outdoor environments.
• Open Path Coverage: Unlike “point” detectors, this unit can monitor a wide area (up to 40m), making it more likely to detect gas clouds that might bypass individual point sensors.
• Fast Response: With a T_{90} of less than 3 seconds, it is one of the fastest gas detection technologies available for industrial safety.
• Self-Diagnostic Capability: The Receiver continuously monitors its own health and the clarity of the optical path, providing “Fault” or “Obscuration” signals if the lens is dirty or blocked.

Important Considerations & Precautions

• Optical Alignment: Precise alignment between the Transmitter and Receiver is vital. Use the Honeywell handheld interrogator (SHC-1) or specialized alignment tools during commissioning.
• Lens Maintenance: While the system compensates for some dirt, the heated optics should be wiped periodically with a clean, soft cloth to prevent “Beam Block” faults caused by heavy salt spray or grime.
• Mounting Stability: The units must be mounted on very rigid structures (e.g., heavy-duty steel posts). Even slight movement or vibration can cause the narrow IR beam to lose alignment over the 40m distance.
• Calibration: The system is factory-calibrated for specific gases. If the target gas changes (e.g., shifting from Methane to Ethane), the response factors must be adjusted via the controller.

Product Applications

The 2108B2001N is used in large-scale industrial facilities where pressurized gas leaks are a risk:

• Offshore Platforms: Monitoring “fence lines” around production modules and wellheads.
• LNG/LPG Terminals: Protecting loading docks and storage tank perimeters.
• Petrochemical Refineries: Surveillance along pipe racks and high-pressure compressor stations.
• Floating Production Storage and Offloading (FPSO): General area monitoring in high-vibration maritime environments.
