Forney’s Intelligent Dynamic Detector (IDD) – Ultra version is designed to accurately detect and discriminate the radiation produced by the combustion of natural gas or light oil.

The Intelligent Dynamic Detector Ultra (IDD-Ultra) is used in conjunction with Forney’s IDD 9000 amplifiers. (For legacy amplifier compatibility, contact Forney.) The IDD-Ultra solid state circuitry amplifies a continuously changing voltage signal transmitted from the Silicon Carbide (SiC) sensor when flame is sensed. This signal is 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 electronics of the detector are potted within the cast steel housing. In addition, the amplifier also initiates a periodic check of the sensor and printed circuit board to verify proper operation of the detector assembly, eliminating the need for a mechanical shutter.

✔︎ High Temperature Silicon Carbide Sensor
High temperature resistance prevents detector head from overheating on the boiler front. Sensitive to ultra violet light radiation prevalent in natural gas and light oil flames.

✔︎ Dynamic Flame Sensing Circuitry
Senses only a dynamic flame signal, discriminates flame from hot refractory and other background conditions.

✔︎ Compact, Durable Assembly
The printed circuit board and sensor are potted within a cast steel housing providing a maintenance free product.

✔︎ Simplified System Maintenance
Quick disconnect, electrical and mechanical connections are used for easy replacement.

✔︎ Fiber Optics
Optional fixtures are available for fiber optic applications.

✔︎ Factory Mutual Approval
Factory Mutual (FM) approval means safe operation and lower insurance rates.
