Pressure mediator with separating membrane and method for the production thereof |
摘要 |
pressure mediator comprising a base body having a membrane bed, wherein said base body has a first material with a first thermal expansion coefficient, in addition to a separating membrane having a second material with a second thermal expansion coefficient that is smaller than the first thermal expansion coefficient The separating membrane is fixed to the base body by its edge area in such a way that the membrane bed is covered by the separating membrane, and the separating membrane also has a relief that is formed by embossing against the membrane bed after the separating membrane was fixed to the base body. Embossing of the membrane relief is carried out at a temperature below critical temperature of less than approximately 10° C. This makes it possible to obtain a constant membrane characteristic line at low temperatures. |
