Honeywell Searchline Excel Infrared Open Path Flammable Gas Detector
SKU
HoneywellAnalyticsSearchlineExcel
The Honeywell Searchline Excel is a hazardous area certified flammable Infrared Open Path Gas Detector. This gas detector is ideal for applications in the harshest environments where reliability and performance are critical. The Searchline Excel provides a vast area of coverage, a very high speed of response and no unseen failure modes.
The unit consists of both a transmitter and receiver, for mounting at each end of the path that is to be monitored. There are three Searchline Excel versions available: Short Range (5-40m), Medium Range (40-120m) and Long Range (120-200m). Hazardous area approvals include European (ATEX), North American (UL) and Canadian (CSA). The receiver output is 3 3-wire 4-20mA selectable sink or source.
Please note that Searchline Excel CSA covers Methane-calibrate versions. A calibration has to be ordered with every Searchline Excel.
The fundamental design of Searchline Excel has remained the same since its original launch and it continues to lead the field.
Searchline Excel is immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning.
The patented optical design used in Searchline Excel has proven itself as the only solution available that fully addresses all the challenges of open-path gas detection. Unlike some competitive devices, it does not try to hide fundamental design inadequacy with the use of software masks that can compromise the unit’s ability to detect gas.
Searchline Excel employs a patented double-band pass filter that fully compensates for all types of fog and/or rain, thereby allowing it to continue to operate accurately and reliably in all climatic conditions.

Why open-path gas detection? Open path detectors complement the use of individual point detectors and offer many significant benefits including:
• Wider area coverage - most likely to pick up any leak- • Very high speed of response
- • NO unrevealed failure modes - no possibility of a blocked gas path to the detector
- • Detector location not as critical
- • Indicates the size of the hazard
Sample and reference detector alignment:
• Reduced sensitivity to alignment
• Guaranteed performance
• Reduced sensitivity to partial obscuration
Improved handheld software:
• Simple confirmation of alignment
• Visual indication of target and current signal levels
• Compatible with existing systems
Improved telescope:
• High Power Rifle Telescope
• Easier to align with greater zoom and magnification
• Robust shock-resistant design
Features & Benefits:
• Fast speed of response provides the earliest warning
• High sensitivity allows low alarm set points
• Alignment-free design makes installation simple
• Alignment-free design makes installation simple
