By connecting the measuring instrument via the diaphragm seal, even the most complicated measuring requirements can be met
By using diaphragm seals (also referred to as chemical seal), pressure measuring instruments can be adapted to even the harshest of conditions within process industries. A diaphragm made of the appropriate material separates the medium to be measured by the measuring instrument. This measuring instrument can be apressure gauge, processtransmitter,pressure switchetc. By connecting the measuring instrument via the diaphragm seal, even the most complicated measuring requirements can be met.
For instance, a diaphragm seal can be used by extreme temperatures or temperature fluctuations, measurements in aggressive, corrosive, highly viscous, heterogeneous or crystallising media. A diaphragm seal can also be used for the integration of pressure and temperature measurement into one measuring point or as an additional safety barrier for explosive or toxic media.
Diaphragm Seals are also commonly used is the food and sterile processing industry. By placing a diaphragm seal between the process and the measuring instrument, a more hygienic connection can be used
