The WIKA 981.18, 981.19, 981.20 and 981.21 in-line diaphragm seals with threaded connections, due to their circular design, can be mounted directly into the pipeline, meaning no special measuring point connection is required. Through the integration into the process line, turbulences, dead spaces, corners and other obstructions can be avoided. For this diaphragm seal WIKA uses a completely round diaphragm, which, due to the unobstructed flow of the media, produces an automatic cleaning of the chamber. The diaphragm seal systems can withstand the cleaning vapour temperatures occurring in the SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal. Assembly of the diaphragm seal and measuring instrument is made via a direct assembly as standard or optionally via a cooling element or a flexible capillary. For the material selection, WIKA offers a variety of solutions, in which the main body and the diaphragm are made of identical materials. Stainless steel 316L (1.4435) is used as standard material. Other special materials are available on request. Measuring systems with WIKA 981.18, 981.19, 981.20 and 981.21 WIKA diaphragm seals are successfully used in the life science industry, in food production, pharmaceutical and biotechnology applications.

The WIKA 990.60 sterile connection diaphragm seal with NEUMO BioControl® connection is particularly suited for use in sterile processes and is adapted to the process via the NEUMO BioControl® housing. This enables a hygienic integration of measuring instruments into pipelines or, by means of block flanges, into tanks or fermenters. The diaphragm seal systems can withstand the cleaning vapour temperatures occurring in the SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal. Assembly of the diaphragm seal and measuring instrument is made via a direct assembly as standard or optionally via a cooling element or a flexible capillary. For the material selection, WIKA offers a variety of solutions, in which the upper body and the diaphragm are made of identical materials. Stainless steel 316L (1.4435) is used as standard material. Other special materials are available on request.
