The invention relates to a sensor block (1) for measuring fluid flow or pressure in a tube (22). The sensor block (1) comprises a sensor (4, 24) and a housing. The housing has an elastic clamp member (11, 12) which is shaped so that it can be plugged onto the tube in the radial direction and, when plugged in, comprises a part of the tube. In addition, the invention relates to a tube (72) which is produced by means of MID technology. The tube (72) comprises tracks (77) and a sensor (24, 84) fixedly connected to the tube (72). In addition, the invention relates to a tube (2, 22) having an opening (49, 36, 46, 56, 66) in the tube wall, which is closed with a sterile filter (28, 38, 48). The tube (2; 22) further comprises two elongate grooves (15) for releasable attachment of a sensor block (1). The invention further relates to a tube (72) having a double pitot tube (6). The invention further relates to a tube (72) with a diaphragm (86) made of porous material. Before and after the orifice (86) an opening (79, 89) is mounted in the pipe wall. Both openings (79, 89) are closed by sterile filters. The invention further relates to a production method in which both a sensor block (1) according to the invention and a tube (2; 22; 72) according to the invention are produced with the same mask set, a same injection molding tool and / or a similar control program part. |
