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 amplifiers
IDD-9000, DR-6101E, RM-IDD and IDD-IIIA.
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 self-
check of the sensor and printed circuit board to verify proper operation of the
detector assembly.
IDD-II Series Flame Detector
Forney’s IDD-II Series Flame Detector
meets the operational flexibility
requirements of utilities through multiple
flame detecting and discriminating
capabilities.
