Abstract
A smoke density monitor for mounting on a ship smokestack. The smoke density monitor provides a transmitter head and a receiver head mounted to a smokestack. The transmitter head and receiver head are optically connected with a density monitor by means of fiber-optic lines. The density monitor is electrically connected to an alarm monitor, which at pre-set smokestack smoke densities activates an alarm and/or shuts down the ship's burner(s). An optional recorder may be connected to the alarm monitor to preserve a record of smoke density. Each transmitter and recorder head has an optical head slidably attached to a head housing for ease of servicing and maintenance.
Claims25
A smoke density monitor comprising an infrared light transmitter head and an infrared light receiver head optically attached to a density monitor by means of fiber-optic line, each said transmitter head and receiver head comprising a head housing which comprises a head chamber, an optical head lens being disposed in said head chamber.
A smoke density monitor comprising a transmitter head and a receiver head mounted on a smokestack, a density monitor optically attached to said transmitter head and said receiver head by means of fiber-optic line, and a sealing air supply in communication with said transmitter head and said receiver head, whereby sealing air from said air supply travels through said transmitter head and said receiver head into a smokestack bore, thus preventing smoke in said smokestack bore from impinging upon optical head lenses disposed within said transmitter head and said receiver head.
