製品概要

The Rosemount 965 uses Multi-Spectrum Infrared Flame Detection with QuadSense™ technology to accurately analyze the multi-spectral signals of hydrocarbon gas or liquid fires using four infrared (IR) sensors. Its ability to differentiate flame sources from non-flame background radiation offers high immunity to false alarms for fires up to 150 ft (45 m) from the device. Five selectable sensitivity levels help you customize settings for your specific application.
