Searchline Excel Edge

Push your detection to the Edge. The Searchline Excel™ Edge Flammable Hydrocarbon gas detector delivers long-range coverage and protection for perimeter and fence-line monitoring.

List of Benefits

  • RELIABLE DETECTION : Fast response to flammable Hydrocarbon gas even in low visibility conditions. Advanced diagnostics including window clarity and alignment accuracy to enable maximum uptime and continuous site protection.
  • EASY TO USE : Honeywell Fixed Platform Universal Mount and advanced alignment scope makes for easy mechanical installation. Incorporates Bluetooth® connectivity for simplified, non-intrusive set-up and maintenance. Just pair the Searchline Excel™ Edge with our intrinsically safe, ruggedized mobile phone; then use the Honeywell Fixed Platform App to interact with the detector.
  • HEAVY DUTY OPERATION : Operates in harsh environments to maintain coverage. Advanced transmitter and receiver optics means that monitoring continues in thick fog long after other detectors cease to provide coverage.
  • AT-A-GLANCE INSTRUMENT STATUS : High Visibility LED HALO ring provides clear indication of device status.Automatic reporting with full logging of alarms, events and maintenance actions.
  • LONG-RANGE MONITORING : Longest range site detection for fence line/perimeter monitoring up to 330 meters (1082 feet). Flat response over a range of target gasses; performance approved.
  • MULTIPLE OUTPUTS : Multiple outputs including 4-20mA, Relays, HART®, Modbus and Bluetooth® communication. Easily integrate the Searchline Excel™ Edge into your existing network.



Designed for long-range perimeter and fence line monitoring applications, the Searchline Excel™ Edge helps protect your people, facilities and processes from combustible gas leaks. When mounted at the edge/perimeter of your facility, it provides long-range monitoring and reliable detection in harsh and changing environments for protection and peace of mind.


The Searchline Excel™ Edge’s innovative optical gas detection capabilities cover a longer range and see through even thick fog better than any other open path gas detectors whether NDIR or laser-based.
