Properties
Application
The heated wall bushings series PSG Heated Wall Bushingsare used in gas analysis for connection of heated sample lines with an installation route leading through walls like e.g. brickworks. A typical application is also leading heated sample lines out of climatic chambers in the automotive industry.
Technology
The heated wall bushings series PSG Heated Wall Bushings with stainless steel jacket made of SS316Ti are designed for installation in brickworks. They are available in various versions. Besides standard dimensions customized solutions are possible. Individualization in relation to length (in dependance on brickworks) temperature and control can be considered. Swagelok-fittings are used for connection of sample lines as standard. Other connections are also possible. Length of the supply line and type of connection plug are also manufactured on customer request. One side has e.g. a screw lid and both sides stainless steel fittings for connection of the sample lines. Internally an insulated stainless-steel tube with heating cable is heated to the desired temperature.
Functions
Due to the homogeneous heating to max. 250°C zones are bridged where temperature could fall below the dew point resp. acid dew point on its way through the brickworks. Thus, condensate formation and therefore clogging as well as washing out of water-soluble sample gas components like e.g. SO2 is prevented.
