The Open Path Combustible system detects hydrocarbon gases by analyzing the absorption of radiation caused by gases in the atmosphere and comparing it to background atmospheric absorption. This is accomplished between a pair of units: a Flash Source and a Detector that can monitor a distance of up to 200 meters.
Open Path Combustible Gas Detectors are robustly designed and can handle the toughest environments: 316L stainless steel housings that meet IP66/IP68 and NEMA 250 6P egress standards; circuit boards epoxy coated for protection; MIL-C-810C testing for humidity, salt, fog, vibration, mechanical shock and temperature extremes; and SIL-2 approval per IEC61508 is a final statement in reliability.
The Spyglass system can replace 20 line of sight point gas detectors, saving up-front costs and ongoing maintenance costs. There are only two units to service, and the maintenance requirements are minimal.There is only one long-life consumable to replace periodically. All of this adds up to lower costs for the customer.
