1. Product Positioning
Exact keyword | Honeywell 2104B2081 Medium-range infrared open-path gas transmitter |
Product type | Medium-range infrared open-path gas transmitter / open-path gas detector |
Detection principle | Infrared line-of-sight gas detection for flammable hydrocarbon gas monitoring |
Buyer intent | Plant safety spare, gas detection replacement, project procurement or installed system matching |
Best use of this page | Confirm the model phrase, review key parameters and prepare a clean B2B inquiry. |
Short conclusion: Honeywell 2104B2081 Medium-range infrared open-path gas transmitter should be reviewed as a configured Honeywell gas detection item, not as a generic gas detector listing.
2. Key Parameters at a Glance
Range class | Medium range |
Path length | 40 m to 120 m according to Honeywell Searchline Excel medium-range product data |
Measuring range | 0 to 5 LEL.m |
Response speed | T90 less than 3 seconds |
Power requirement | 18 to 32 VDC |
Output signals | 4 to 20 mA normal operation, RS485 / Modbus options depending on configuration |

3. Model and Configuration Reading
Honeywell | Brand context for fixed gas and flame detection instruments. |
2104B2081 | Buyer-supplied model number. Keep it unchanged in title, content and inquiry subject. |
Medium-range | Important range clue. Verify that the site path length is within the 40 m to 120 m medium-range window. |
Infrared open-path | Indicates line-of-sight gas detection rather than a point detector installed at one sampling location. |
Gas transmitter | Check receiver/transmitter set details, output signal and controller interface before quotation. |
Do not remove the model number
A shortened request such as Honeywell open path detector may lose the most useful purchasing detail. Use Honeywell 2104B2081 Medium-range infrared open-path gas transmitter as the main inquiry line.
4. Signal and Status Checks
Normal output | 4 to 20 mA for 0 to 5 LEL.m normal operation |
Fault state | 0 mA or 2 mA fault behavior may apply by configuration |
Beam blocked | 2.5 mA beam blocked status is listed in Honeywell product data |
Dirty optics | 3 mA dirty optics status supports maintenance awareness |
Over range | 21 mA over range status should be considered in control-system setup |
Digital integration | Modbus RS485 can be used through compatible Honeywell interface options |
5. Site Application Fit
Honeywell 2104B2081 Medium-range infrared open-path gas transmitter is suitable to discuss for open-path flammable gas monitoring where line-of-sight coverage is required.
Common application areas include gas transport, pipelines, chemical processing plants, offshore platforms, storage zones and large buildings.
Medium-range selection should be checked against actual transmitter-to-receiver distance and mounting visibility.
Alignment tolerance, vibration, weather exposure and obstacle risk should be reviewed before replacement.
For safety systems, confirm alarm handling, controller input, maintenance procedure and site approval requirements.
6. Quotation Preparation
Send the full keyword: Honeywell 2104B2081 Medium-range infrared open-path gas transmitter.
Attach nameplate photos, receiver/transmitter photos and any system label photos.
