In-line diaphragm seals 1530 with connection DIN 11851 Main Features Directly integrated in the pipe Excellent cleaning behaviour Wetted parts 1.4435 / 1.4404 (316L) or 1.4571 (316Ti) Compatible to SIP and CIP processes Easy and fast installation Applications Food & Beverage Laboratory & Medical Description This in-line diaphragm seals are used to design hygienic process connections for pressure gauges and protect the pressure gauges from high temperatures and aggressive process fluids. Process connection DIN 11851 In-line diaphragm seals with hygienic process connections ensure efficient cleaning processes and avoid pollutions and developing of bacterias in hygienic production processes. Body material Diaphragm seals can be mounted to mechanical pressure gauges, switches or transmitters directly or with a flexible capillary. The filling fluid of the measuring system has to be choosen compatible to the application. For hygienic applications a choice of FDA conform filling fluids is available.
