Abstract
The invention relates to a pressure transducer assembly (1; 24) connected to a process circuit of a process plant by at least one fluid line (5; 26, 27; 61). There is a flange connection (7; 33) between connections on the process circuit and the fluid line and a flange connection (9; 35) between a connection block (3; 32) and the fluid line (5; 26, 27; 61). Each flange connection has a flange (8, 11; 34, 37; 53; 62) on the fluid line. According to the invention, at least one of the flanges (8, 11; 34, 37; 53; 62) on the fluid line is made in two parts and consists of a flange connection piece (14; 46, 50; 54) screwed to an end of the fluid line. The flange connection piece provided with an axial passage bore (18; 47; 55) and of a flange element (15; 48, 51; 56, 58; 64) having a sealing face (19). A slipped-over separate flange (22; 49, 52; 57) affixed to a contact surface (10; 36; 59) which reaches over the flange element (15; 48, 51; 56, 58; 64) and connects it to the contact surface (10; 36; 59) so as to press with a sealing face (19) of the flange element against the contact surface (10; 36; 59). A great flexibility is provided by a choice among different flange forms, and at th…
