Description
For Use With (Equipment): Searchline Excel Infrared Open Path Flammable Gas Detector System
Unit Size: Each
Searchline Excel line-of-sight infrared open path gas detection system with XNX TransmiterOpen path detectors complement the use of individual point detectors and offer many significant benefits including:
• Reliable flammable gas detection, proven in use
• Wider area coverage - most likely to pick up any leak
• Very high speed of response
• Failsafe - no unrevealed failure modes - no possibility of blocked gas path to detector
• Detector location not as critical
• Indicates size of hazard
• Simple set up and commission
• Replaces multiple point devicesThe patented optical design used in Searchline Excel has proven itself as the only solution available that fully addresses all the challenges of open path flammable 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.Searchline Excel is totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning. This is achieved by using a xenon flash lamp that is actually brighter than the sun at the infrared detection wavelengths and solid state detectors with a wide dynamic range. The lamp is also modulated to have a unique pulse duration and shape. The receiver then uses high speed digital signal processing to validate that all the signals received have this unique signature and rejects any extraneous signals.Features and Benefits:
• Double band pass filters that fully compensate for all types of fog, rain and/mist interference
• 100% Solar Immune
• Correct operation under partial obscuration conditions
• High vibration resilience
• Radially symmetrical and bonded window heating delivers good low temperature performance
• Coaxial optics delivers best in class performance and resilience to partial obscuration
• Fully temperature compensated solid state detectors
• Low power consumption in all conditions
• Simple ‘lock on’ alignment tool
• No extra ‘software alignment’ required
• Higher power and more robust design telescope
• Optional Modbus RS485 multi drop output
• FM hazardous area and performanceXNX TransmitterXNX is designed for flexible integration, simple installation, user-friendly operation and straight-forward maintenance. It is ideal for use with a range of gas monitoring controllers or industry standard PLCs. The introduction of HART Enhanced Device Descriptor Language (EDDL) software provides users with an at-a-glance indication of the health of their gas detectors in the field.Features:
• Large, backlit, easy-to-view LCD display offers multisensory indicators (visual icons, colored buttons, text, etc.) to display gas and sensor readings
• User interface supported by 8 selectable languages
• Self-test and fault indication features
• Non-intrusive, one-man operation
• Quick calibration with auto-inhibit
