Application scenarios: including offshore platforms and vessels (FPSOs), downstream chemical processing plants, natural gas transportation and pipelines, large storage areas and buildings, perimeter inspections, etc.

Product Evolution: Honeywell Analytics launched the original Searchline in 1987, pioneering the design of open circuit infrared combustible gas detectors. Searchline Excel was launched in 1998 and became an industry standard through continuous improvement and high-quality manufacturing and control processes. It is often used in conjunction with Searchpoint Optima Plus as the primary combustible gas detector and auxiliary combustible point detector.

Core advantages and characteristics

Performance advantages

By using a dual bandpass filter, it can fully compensate for various fog, rain, and/or mist interferences.

100% unaffected by the sun, can work normally under partial shading conditions, and has strong anti vibration ability.

Radial symmetrical and bonded window heating, with good low-temperature performance; Coaxial optical systems provide the best performance and resistance to partial occlusion in their class.

Full temperature compensated solid-state detector with low power consumption under all conditions, equipped with a simple “locking” alignment tool, without the need for additional “software alignment”.

The telescope is designed with higher power and sturdiness, and can be equipped with Modbus RS485 multi-point output. It has obtained FM hazardous area and performance certification.

Advantages of open circuit gas detection: As a supplement to point detectors, it has reliable combustible gas detection (verified through use), wider coverage (most likely to detect any leaks), extremely fast response speed, fail safe (no unexposed fault modes, no possibility of gas path blockage), less critical detector position, can indicate the magnitude of danger, simple setup and debugging, and can replace multiple point devices.

Unique technological design

Patent optical design: It is the only solution that can fully address all challenges of open circuit combustible gas detection, using patented dual bandpass filters that can operate accurately and reliably in all weather conditions without relying on software masks that may affect gas detection capabilities.

Coaxial optical design: The unique coaxial optical design makes it the only open circuit gas detector that can operate normally under partial shielding conditions without generating false alarms, while non coaxial instruments may experience false alarms due to differential attenuation.

True Alignment System: Good installation is the key to achieving optimal performance for open circuit gas detection systems. This system can achieve precise alignment without the need for software based alignment tools for further adjustments. During installation, a telescope is used to visually inspect the path to ensure there are no physical obstacles.
