| 摘要 |
<p>The present invention relates to a device for measuring the smoke density of exhaust gas in a chimney using an infrared sensor and, more specifically, to a smoke density measuring device for measuring the smoke density of exhaust gas discharged through a chimney using an infrared sensor regardless of luminous intensity and the inference of disturbance light (Especially, sunlight). The device for measuring the smoke density of exhaust gas in a chimney using an infrared sensor comprises a smoke chamber (10) coupled to stack adaptors installed in the side surfaces of a chimney and having a through-hole (12) therein; a fan chamber (20) attached to one side of the smoke chamber and having a blow fan attached therein to supply wind to the smoke chamber; an infrared sensor (30) installed in one end of the smoke chamber and having an infrared emitting part for emitting the light of an infrared waveband and an infrared receiving part for detecting the light emitted from the infrared emitting part and reflected by the smoke of the exhaust gas in the chimney; and a control board (40) for displaying the smoke density of the exhaust gas measured by the infrared sensor in the chimney.</p> |
