Description

Monitoring hazardous industrial environments requires reliable and continuous gas detection, which is provided by the Honeywell 2108B2101 infrared hydrocarbon gas detector. Operating as part of the Searchpoint Optima Plus series, this point gas detector utilizes dual-wavelength infrared absorption technology to deliver fast and accurate gas monitoring in potentially explosive atmospheres. Designed for challenging field conditions, the device is highly resistant to common sensor poisons such as silicones, sulfur, and lead, ensuring long-term operational stability and minimizing maintenance requirements.

The 2108B2101 detector features a robust 316 stainless steel housing that provides exceptional protection against harsh weather, seawater, and mechanical impacts. Its optical design features a heated optical chamber to prevent condensation, maintaining high measurement integrity even during rapid temperature fluctuations. This instrument integrates into existing industrial safety infrastructures via a standard 3-wire 4-20mA output configuration, making it compatible with a wide range of PLCs, DCSs, and safety controllers.

Features

• Dual-wavelength infrared detection technology ensures fail-safe operation and high stability.
• Immunity to catalytic poisons including silicones, sulfur, halogens, and heavy metals.
• Fast speed of response (T50/T90) for rapid leak detection.
• Heated optics eliminate the risk of condensation and optical drift.
• Robust 316 stainless steel construction suitable for offshore and onshore environments.
• Low power consumption design with local diagnostic capabilities.
• Capable of operating in completely inert atmospheres where catalytic sensors fail.

Applications

• Offshore oil and gas production platforms
• Onshore petrochemical refineries and processing plants
• Gas transmission stations and compressor facilities
• Chemical manufacturing plants
• Wastewater treatment facilities with hydrocarbon hazards
• Power generation sites utilizing natural gas

Installation Guidelines

To ensure optimal performance and safety, follow these fundamental installation principles:

• Mounting Orientation: Mount the gas detector horizontally to prevent dust, water, or debris from accumulating on the optical window.
• Positioning: Place the detector near potential leak sources or at locations where hydrocarbon vapors are likely to accumulate, taking gas density and local airflow patterns into account.
• Wiring and Grounding: Ensure the device is connected using shielded cable to prevent electromagnetic interference. Properly ground the housing in accordance with local explosion-proof wiring codes.
• Hazardous Areas: Maintain the integrity of explosion-proof cable glands and conduit seals to preserve the certified safety rating of the installation.
