Description

The diaphragm seal can protect the measuring instrument from corrosive, viscous, crystalline, corrosive, environmentally harmful or toxic media. Diaphragm made of appropriate materials can separate the measuring instrument from the measured medium. Therefore, the measuring instrument can be used for the most difficult measurement as long as the appropriate diaphragm seal is equipped. The filling liquid inside the system (the most suitable liquid can be selected according to the specific application) can transmit the pressure to the measuring instrument by hydraulic means. We can provide diaphragm seals of different designs and materials to meet all application requirements. When selecting diaphragm seals, users should pay attention to two important standards: one is the type of process connectors (flange, thread and sterile connector); The second is the basic manufacturing method H22 diaphragm seal with clamp joint is specially designed for aseptic processing applications, which can be integrated into the process flow through the clamp, and can ensure good cleanability. The diaphragm sealing system can withstand the high temperature of clean steam in the SIP process and realize the aseptic connection between the measured medium and the diaphragm seal. Diaphragm seals and measuring instruments can be assembled directly or through cooling elements or flexible capillary tubes. In terms of material selection, Rodweiger provides a variety of solutions, and the upper chamber and liquid receiving part of the diaphragm seal can be made of the same or different materials. As an alternative, the wetted part can be electropolished.
