Flame Detection in Airplane Hangars
Avoid dangerous situations with dependable flame detection solutions
Accurate & Reliable Flame Detection at Long Distances & Over Wide Area
Highly combustible aviation fuel leaks can occur in aircraft hangars and within fuel storage areas. These fires can be extremely dangerous, as well as extremely costly as damage to the aircraft can occur. While many flame detection solutions typically focus on the aircraft itself, it’s important to also consider monitoring the aircraft hangar. Continuous monitoring for flames can help detect and prevent dangerous fires. It’s important that the flame detectors avoid false alarms and have a wide coverage area. Rosemount™ 975 Flame Detectors help protect personnel and aviation equipment by detecting fuel and gas fires at long distances and over wide areas. These flame detectors also have a high immunity to false alarms.

The Rosemount 975MR Multi-Spectrum Infrared Flame Detector accurately analyzes the multi-spectral signals of hydrocarbon gas or liquid fires by utilizing four separate IR sensors. The 975MR detects fuel and gas fires at long distances. For example, this product will detect a 1 ft2 (0.1m2) gasoline pan fire at 300 ft (90 m). The 975MR also provides a high immunity to false alarms and enhanced overall coverage range.
- Maximum flame detection range of up to 300 ft (90m)
- Six sensitivity levels, adapting to any application
- High speed response time under 50 msec (Exp./1 sec)
