Forney fs Intelligent Dynamic Detector (IDD) II Series is designed to accurately detect and discriminate the luminous flames produced by burning oil, coal, and lignite fuels.
The IDD-II (Filtered) flame detector is typically used for sensing heavy fuel oil and coal flames. The IDD-IIU (Unfiltered) flame detector is typically used for sensing light fuel oil flames. The IDD-IIL (Lignite) flame detector is specifically designed to sense low flame frequency produced by lignite and high ash coal flames.
The IDD-II Series is used in conjunction with Forneyfs supporting amplifiers IDD-9000, DR-6101E, RM-IDD and IDD-IIIA.
