METHOD FOR FILLING A PRESSURE TRANSMITTER

摘要

The invention relates to a method for permanently filling a pressure transmitter via a filling opening located in a housing wall of the pressure transmitter, comprising the following steps: filling the pressure transmitter with a transmitting liquid via the filling opening; arranging a sealing element in the filling opening such that transmitting liquid can no longer exit through the filling opening; arranging at least one nano- or microreactive material at least in the region of the housing wall located around the filling opening; arranging the closure element such that the closure element at least partially covers the nano- or microreactive material and at least partially covers the sealing element; triggering a local exothermic reaction around the closure element with the housing wall by means of the nano- or microreactive material.
