Abstract
The present disclosure discloses process seals having a form retaining core and a coating of a thermoplastic sealing material for pressure sensors. The process seals can be replaced in simple manner, especially essentially without loss of measurement accuracy. The process seals are characterized by features including that they are pre-aged in a pre-aging method performable in a reproducible manner and insertable in the pressure sensor as replaceable components, wherein the process seals were clamped during the pre-aging method in a clamping apparatus exerting a clamping force thereon, wherein the clamping apparatus has a clamping geometry surrounding the process seal clamped therein, which is essentially identical to the clamping geometry surrounding the process seal in the pressure sensor.
