2110B1822 HONEYWELL

The Honeywell 2110B1822 is a specialized component within the Searchline Excel series, which is part of Honeywell's Analytics line for open-path gas detection. This specific part number typically refers to a Short Range Receiver unit. It is engineered to detect the presence of flammable hydrocarbon gases over a specified distance by monitoring the absorption of infrared light. The Searchline Excel system consists of an infrared transmitter and this receiver, working in tandem to provide a continuous line-of-sight safety barrier in industrial environments.

Product Specifications

The following technical parameters define the operational limits and characteristics of the 2110B1822 receiver:

• Detection Technology: Open-path infrared absorption (Point infrared technology adapted for open-line paths).

• Target Gases: Methane, Ethane, Propane, Butane, Pentane, Ethylene, and other flammable hydrocarbons.

• Operating Range: This "Short Range" model is optimized for distances typically spanning from $5 \text{ meters}$ to $40 \text{ meters}$ ($15 \text{ feet}$ to $130 \text{ feet}$).

• Signal Output: Standard 4-20mA analog output with HART digital communication capability for diagnostics and configuration.

• Response Time: Very fast response, typically $T90 < 3 \text{ seconds}$ under standard conditions.

• Power Supply: $18 \text{ VDC}$ to $32 \text{ VDC}$ (Nominal $24 \text{ VDC}$).

• Material Construction: Typically manufactured using 316 Stainless Steel for the housing to provide maximum corrosion resistance in harsh offshore and onshore environments.

• Ingress Protection: Rated at IP66 and IP67, ensuring the unit remains functional even when exposed to heavy seas or high-pressure water jets.

• Operating Temperature: Designed to function in extreme climates, generally ranging from $-40°C$ to $+65°C$.

Product Advantages

• High Sensitivity and Speed: Unlike point detectors that wait for a gas cloud to reach them, the 2110B1822 detects a gas cloud anywhere along the path, providing a much faster warning for large leaks.

• Robustness Against Interference: The system is designed to be immune to interference from sunlight, rain, fog, or "vibration-induced" misalignment through the use of sophisticated patented optical filtering and alignment compensation.

• Reduced Maintenance: Since one pair (Transmitter/Receiver) covers up to $40 \text{ meters}$, it replaces multiple point detectors, significantly reducing the cost of installation, wiring, and routine calibration.

• Fail-to-Safety Operation: The unit is self-monitoring and will signal a fault if the beam is completely blocked or if internal hardware failures occur, ensuring the operator is never unaware of a blind system.

Important Considerations and Precautions

• Optical Alignment: Precise alignment between the transmitter and the 2110B1822 receiver is critical. Even slight physical shifts in the mounting structure can lead to beam loss or "beam block" faults.

• Cleanliness of Optics: While the system is tolerant of some obscuration, excessive buildup of salt, snow, or dirt on the lenses can degrade performance. Regular inspection and cleaning with approved materials are recommended.

• Hazardous Area Certification: Ensure the specific certification (ATEX, IECEx, or UL/CSA) matches the requirements of your installation site. The unit must be installed by trained personnel following "Explosion Proof" or "Flameproof" wiring practices.

• Avoid Physical Obstructions: The line of sight must remain clear. Permanent or temporary obstructions (such as parked vehicles or scaffolding) will cause a system fault and render the gas detection ineffective.

Product Applications

The 2110B1822 Short Range Receiver is primarily utilized in high-risk industrial sectors where large-scale gas leaks must be detected instantly:

• Oil and Gas Production: Protecting offshore platforms, FPSOs (Floating Production Storage and Offloading), and onshore wellhead sites.

• Refineries and Petrochemical Plants: Monitoring fence lines, tank farms, and pump rows where hydrocarbon vapors may accumulate.

• Gas Transmission and Pipelines: Installed around compressor stations and metering stations to monitor for high-pressure leaks.

• Chemical Storage Facilities: Providing a safety perimeter around loading docks and chemical storage tanks.

• Power Generation: Monitoring gas turbine enclosures and fuel supply lines.
