Title: Optical density measuring device in smoke channel - has calibrating device with radiator and receiver
Inventor: HASS KARL-HEINZ
IPC: G01N21/53
Filed: 1974-06-26
Abstract: The smoke channel has two flanged tube sockets at its opposite sides, on which the radiator and receiver or a reflector are mounted. A calibration tube is inserted into the tube sockets, screening the light path against smoke. This tube has a nonreflecting inner surface so that possible reflections do not upset the measuring. A suitably coloured coating serves this purpose. The calibration tube contains smoke and dust-free air since air pouring out of the tube supports flows through the tube while it is being fitted and thereby removes residual smoke and dust. After fitting in the supports and cleaned with a stream of fresh air both ends of the tube are screened against smoke by the air from the blower.
