Rosemount 975 Multi Spectrum IR Flame Detector

Feature & Principle

It adopts multi-spectrum infrared detection principle. It identifies the unique flicker frequency and spectral characteristic of hydrocarbon flame. Advanced signal algorithm suppresses interference from sunlight, hot surfaces and arc light, greatly reducing false alarm rate. It integrates self-test function, can continuously check sensor and circuit health status. It is equipped with explosion-proof stainless steel housing, suitable for hazardous area Class I Div 1 / ATEX zone 1. It can connect to fire alarm system or DCS via 4-20mA and dry contact relay signal.
