Deskripsi
Flame Detector Discrete Detectors (Separate Amplifier)
Model : IDD-II / IDD-IIU
Brand : FORNEY
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-II Series is used in conjunction with Forney’s supporting amplifier the IDD-9000.
When a flame is sensed, the IDD-II’s solid-state circuitry amplifies the continuously varying voltage signal emitted by the lead sulfide sensor. The signal is sent via a four-conductor cable to an amplifier, which processes the signal and provides an output to the burner management system. For trouble-free operation, the detector electronics are enclosed in a cast steel housing. Furthermore, the amplifier initiates periodic electronic self-tests of the sensor and printed circuit board to verify proper operation of the detector assembly.
