Abstract
The present invention relates to a pressure transducer assembly (1; 24; 39) on a process circuit (2; 29, 30; 48, 49) as is used in a process plant, whereby the process circuit (2; 29, 30; 48, 49) is capable of carrying a hot fluid. Furthermore at least one fluid carrying measuring line (5; 26, 27; 40, 41) is provided between the process circuit (2; 29, 30; 48, 49) and a valve (4) of the pressure transducer (3; 25; 42), and/or transducer. Furthermore first and second flange connections (6, 10; 31, 32; 44) are provided between connections on the process line 9)2; 29; 30) and the fluid measuring line (5; 26, 27; 40, 41) as well as between the valve (4) and the fluid measuring line (5; 26, 27; 40, 41). These flange connections are connected to each other by means of nuts and bolts (9, 13; 38). According to the invention, a sealing, heat insulating intermediary layer (16, 20; 37; 45) is installed between a flange (7; 33) on the process circuit side and the first flange (8; 34) on the fluid measuring line side and/or between the flange (11; 35) on the valve side and the second flange (12; 36) of the fluid measuring line side. Thanks to this heat insulating intermediary layer (16, 20; 37;…
