Rosemount-975MR Multi-spectrum Infrared Flame Detector

Rosemount™ 975MR Multi-Spectrum Infrared Flame Detector

Product Description

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.
