IDD-Ultra UV Flame Detector

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.
