Product Overview

Forney’s 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 Forney’s supporting amplifier the IDD-9000.  (The DR-6101E, RM-IDD and IDD-IIIA are now obsolete – replaced with the IDD9000 Amplifiers).

The IDD-II’s solid state circuitry amplifies a continuously changing voltage signal transmitted from the lead sulfide sensor when flame is sensed. The signal is then sent to the amplifier by way of a four conductor cable. The amplifier processes the signal and provides outputs to the burner management system.

For trouble-free operation, the detector electronics are potted within the cast steel housing. In addition, the amplifier also initiates a periodic, electronic selfcheck of the sensor and printed circuit board to verify proper operation of the detector assembly.
