Test function

The contamination of the light-receiving
window and the operating status of thei nte r n a l c i rc u i t a re c h e c ke d b y t h epseudo-ﬁre light, and a trouble signal is sentin case of an abnormality.

Contaminationdetectionfunction

When the contamination of the light-receiving
window is detected during the test and thepermissible value is exceeded, a trouble signal
is transmitted.

Power supply
When the power supply voltage drops below
voltage monitoring about 18.5 V, a trouble signal is transmitted.

FLAME DETECTOR

Explosion-Proof-Type Infrared Three-Wavelength Flame Detector

PDCJ002-E

The PDCJ002-E detects the CO2 resonance radiation and f licker that are unique characteristics of f lames.Despite its highsensitivit y, the PDCJ002-E has fewer false alar m perfor mance and can be installed under direct sunlight or ar tif icial
lighting such as sodium lamp, mercury lamp, f luorescent lamp, germicidal lamp, halogen lamp, etc.

Nohmi's infrared three-wavelength ﬂame detector (PDCJ002-E) is designed to detect the presence ofﬁre from the radiant energy produced by ﬂames (CO2 resonance radiation) and ﬂame ﬂicker. ThePDCJ002-E quickly detects ﬁre even in places with ventilation ﬂow, external air, or high ceilings wheredetection is often diﬃcult for the ordinary detectors. This high-sensitivity detector is also suitable forﬁre detection in explosion-proof areas.

Reliable ﬁre detection

The energy intensity of the three wavelength bands in the CO2 resonance radiation band and the ﬂicker ofthe ﬂame are judged as “ﬁre” by an advanced algorithm to suppress false alarms.

Wavelength〔μm〕 The red band is the wavelength band detected.

The infrared energy emitted from ﬂames has the spectral characteristics of a peak in the wavelength of the 4.4μm band. This is called CO2 resonance radiation. As shown above, this feature is quite diﬀerent from the spectral
characteristics of infrared rays emitted by objects other than ﬂames.
Another characteristic is that the infrared energy emitted by the ﬂame ﬂickers at a frequency of 1 to 15 Hz.
Furthermore, the respiratory action of the ﬂame always causes ﬂuctuation of the amount of radiation.
Nohmi's infrared three-wavelength ﬂame detector monitors the three wavelength bands of CO2 resonanceradiation. It is able to accurately detect ﬁre by recognising the unique property of ﬂames in terms of their energy
intensity, ratio, etc, CO2 resonance and ﬂicker.
