Description

The diaphragm seal can protect the measuring instrument from corrosive, viscous, crystalline, corrosive, highly viscous, 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. H27 diaphragm seal adopts flange connection and flat diaphragm design, which is applicable to all current standard flanges, and can be installed in pressure measuring instruments without blind flange. Diaphragm seal and measuring instrument can be directly assembled (standard configuration), or assembled through cooling element or flexible capillary tube (optional). In terms of material selection, a variety of solutions are provided. The upper chamber and diaphragm of the sealing diaphragm can be made of the same or different materials. Diaphragm and sealing surfaces can also be provided with spraying or coating. The measurement system equipped with H27 diaphragm seal has been successfully used in the chemical and petrochemical industries with high measurement requirements worldwide.
