Description
Open Path Gas Detection Across Industrial Areas
The Honeywell Searchline Excel is an open path infrared detector for flammable gas hazards. Using a transmitter and receiver across a monitored beam path, it complements individual point detectors with wider-area coverage for industrial gas monitoring.
Designed for Challenging Outdoor Conditions
Searchline Excel uses optical filtering to compensate for interference from fog and rain. Its optical design resists interference from sunlight and other radiation sources, while heated windows and contamination-resistant optics support operation in demanding environments.
Key Features
- Fast response: T90 less than 3 seconds under normal operating conditions.
- Infrared sensing immune to catalytic poisons and suitable for use in inert atmospheres.
- Optical design with resilience to partial obscuration and reduced sensitivity to alignment.
- Functional gas test facility for system checks.
- 4–20 mA output for gas monitoring system integration.
- Optional MODBUS RS485 integration using suitable DX100(M) or XNX equipment.
- 316 stainless-steel enclosure and IP66/IP67 ingress protection.
Path Length Options
- Short range: 5–40 metres.
- Medium range: 40–120 metres.
- Long range: 120–200 metres.
Technical Highlights
- Measuring range: 0–5 LEL·m, representing gas concentration integrated across the monitored path rather than a point concentration.
- Operating temperature: −40°C to +65°C.
- Power requirement: 18–32 VDC.
Typical Applications
Offshore platforms and FPSO vessels, chemical processing plants, gas transport and pipelines, industrial perimeter monitoring, and large storage areas or buildings.
Select the Right Configuration
This listing describes the Searchline Excel range, not a single orderable part number. Confirm the required path length, target gas calibration, transmitter and receiver configuration, mounting accessories, communication interface and hazardous-area approvals against current technical documentation. Proper installation and alignment are required.
