It can be used as well to connect to a vessel either than to a pipe. Beside the outstanding price, the robust equipment is the biggest advantage. The hygienic conditions in this connection are, due to the big, undefined sealing, not the best. The sensor can’t be mounted complete flush to the process.,Different parts of the dairy connection DIN 11851 from left to right: nut, threat part, conical part, seal,Dairy process connection DIN 11851,3,,Dairy process connection DIN 11851,4,,Annotation: The announced successor of the 11851 is the 11864 connection. Here we find a defined load and a very small surface of the sealing to the process. The DIN 11864 follows the engineering rules of EHEDG (European Hygienic Equipment Design Group). Unfortunately, no unique standard has developed so far. 2 different versions are described: Form A is a construction using an O-Ring seal. Form B is using a special formed sealing.,Example: aseptic connection acc. to DIN 11864 A (Photo: Stericom / GEA),Aseptic connection acc. to DIN 11864,5,,Example, aseptic connection acc. to DIN 11864 (Photo: Stericom von GEA - Version A)Advantage of this sealing concept is the standard O-ring. It is easy and cheap to purchase. Disadvantage of the O-ring is his susceptibility against vacuum.,Aseptic connection acc. to DIN 11864,6,,Series 2 - sealing version A, flange,We also have to differentiate between flange and screwed connection. For both versions, two series each exist. Series 1 is the screwed, series 2 is defined as the flange version. The sealing is equal for both.,Series 1 - sealing version A, screwed,Aseptic connection acc. to DIN 11864,Series 1 - sealing version B,7,,Series 1 - sealing version B,The version B is also built in 2 series, one with screwed connection (version 1) and one with flange (version 2). The sealing is guided in a defined room. There is no problem with vacuum, but the purchase and asset management boroughs more expenses and efforts.Because of the big installed base of the DIN 11851 and the fact, that there are several connections built to full fill DIN 11864, this new standard could not prevail so far.,Aseptic connection acc. to DIN 11864,8,,Annotation: This connection is one Neumo approach for hygienic connections. It follows the aim of the DIN 11864. The defined load of the small sealing in a defined and completely filled room prevents the sealing from being stressed during installation, and from “breathing” while temperature changes. Disadvantage are the small and sensitive edges that easily can be damaged while handling. The sealing is realised by a standard O-ring.,Aseptic connection - Neumo,9,,Annotation: The BioConnect was especially prepared for hygienic use in the Pharmaceutical Industry. It follows the same argumentation then the Neumo Aseptic Connection.,BioConnect - NEUMO,10,,Annotation:The SMS process connection is mostly used in Scandinavia and France. Sensors can be connected neither to pipes or vessels. Advantage is the robust construction and the low price of this equipment. Disadvantage is the big sealing with all the resulting hygienic problems,SMS-connection,Process connection SMS,11,,Threat, nut, sealing,Process connection SMS,12,,Annotation:The clamp connection is as well used in food as in the pharmaceutical industry. It is the standard connection in USA/ NAFTA countries (Tri Clamp). The clamp is used for connections to pipes and to vessels ISO Clamps are standardised connections for ISO pipes. In the ISO world, there are also clamps following DIN 32676. They are used for pipes following DIN 11850.The clamp connection is sealed by a flat form sealing. The load to this seal is created at all points by the clamp even. The seal is stressed less than in a DIN11851connection, but it is more complicated to install.,Parts of the clamp-connection: 2 x clamp-welding parts, clamp, sealing,ISO-CLAMP-Process connection,ISO 2852 - Clamp-connection,13,Annotation:Beside the clamp connections for the DIN/ISO-world, mostly for USA/NAFTA, the company TRI Clover is preparing the TRI-CLAMP® - connection. The extend is just close to the ISO clamps.Beside the soft plastic sealing, for TRI-CLAMP®-connections there is also sealing available made from peek. This sealing ease the installation of the connection, because it sticks on the clamp part.,TRI-CLAMP®-Prozessanschluss,TRI-CLAMP®-connections,14,,Annotation:The Varivent®-Inline housing is used to install instruments in pipes. We achieve a good flush mounted installation. The instrument is mounted direct in the flow. Because of the con-struction, there is no pressure loss in the housing. The design ease CIP cleaning. The connection is sealed by a standard O-ring. The fastening is realised with a clamp. This might result in a bad surprise, if the clamp is opened while there is some pressure left on the process.,。
