德國AB MDM 7952  PN 1000 female

緊湊高壓內螺紋連接隔膜壓力表

Diaphragm Seals Compact Type，

High Pressure Connection， PN 1000
Model MDM 7952

      Application
      Diaphragm seals model MDM 7952 were especially developed for high pressure applications. They are provided with a high pressure process connection. Despite of the high nominal pressure， these diaphragm seals are designed very compact and suitable also for narrow mounting spaces. Diaphragm seals model MDM 7952 are often applied in chemical plants with discerning process media at high pressure. Various special materials are available.

      Important information about advantages， applications， and features can be found in our model overview 7000 where you will also find an overview of our other chemical seal series. Please note especially the explanations about the influences of temperature and other special operating conditions， and the requirement of detailed ordering information resp. inquiries.

      Please use our check list for pressure measuring instruments with chemical seal to ensure the completeness of all required ordering information (to find at our website， under "PDF-Download"). You can receive the check list in printed version with mail upon request.

      Construction
      The diaphragm is welded to the upper and the lower housing.
      No additional sealing inside of the diaphragm seal required due to fully welding. The complete measuring system is evacuated， completely filled with a suitable high pressure filling liquid and hermetically sealed.
