Product Introduction
The Honeywell Searchline Excel 2104B2071 is an industry-standard open path infrared flammable gas detection transmitter engineered for critical safety monitoring in hazardous industrial environments, such as oil and gas facilities, petrochemical plants, and offshore platforms.
Designed specifically for short-range applications (5 to 40 meters / 15 to 130 feet), this transmitter uses advanced infrared absorption spectroscopy (utilizing a high-intensity xenon flashlamp and solid-state detectors) to reliably detect hydrocarbon gas clouds over a line-of-sight path, offering immunity to false alarms caused by solar radiation, rain, or other environmental interferences.

Compliance & Standards Alignment
- Certified for hazardous area installation (ATEX, IECEx, UL, CSA, FM, and TR-CU safety classifications).
- Engineered to withstand severe weather events, heavy winds, and vibration while maintaining optical alignment integrity between the transmitter and receiver heads.
Technical Note: The 2104B2071 transmitter must be paired with a compatible Searchline Excel receiver and calibrated for the specific target hydrocarbon gas type (e.g., methane or propane) to ensure accurate lower explosive limit (LEL-meters) measurement.
Storage & Asset Preservation Guidelines
- Store the optical transmitter assembly in its original protective packaging, ensuring the optical lens window is protected from scratches, dust, and chemical residues.
- Maintain warehouse storage environments where temperature is controlled and relative humidity remains below 60%.
- Avoid mechanical impact or stacking heavy objects on top of the instrument housing to prevent damaging the explosion-proof threads or internal optical assemblies.
Physical Installation Prerequisites
- Ensure that all local power feeds and loop circuits are completely de-energized and locked out (LOTO) prior to mechanical mounting or electrical wiring.
- Mount the transmitter securely onto rigid structural steel or dedicated alignment brackets to eliminate micro-vibrations that could misalign the optical beam path over the 5–40m span.
- Verify that cable entries use certified explosion-proof cable glands and that seals are properly tightened to maintain environmental integrity (IP66/IP67 ingress protection).
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this gas detector component?
A: Industrial gas analysis and detection apparatus typically classify under HS code 9027.10 (Gas or smoke analysis apparatus) or 9031.80. Confirm classification parameters with your licensed customs broker.
Q: Can the 2104B2071 short-range transmitter be used with a long-range receiver?
| No. Searchline Excel optical components are strictly tuned and classified by range category (Short Range: 5–40m vs. Medium/Long Range). Ensure your transmitter and receiver optical configurations match.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions and available surplus inventory levels; contact our technical sales desk for a formal, time-sensitive quotation.
