IDD Detector

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.
