Abstract
A method is provided for connecting a diaphragm to a housing of a pressure or force sensor, wherein a measurement element is attached in the housing and can capture a load acting from the outside onto the diaphragm during the use of the finished sensor. A housing ring surface or the housing is situated opposite a diaphragm ring surface of the diaphragm, which are subjected to compressive loading by the load during use of the sensor. A first connection is produced in an inner region between the housing ring surface and the diaphragm ring surface until they rest against each other radially outside the first connection. Then a second connection connects the housing ring surface and the diaphragm ring surface to one another radially outside the first connection up to a shared outer edge. Here, a defined connection depth of the entire double connection is maintained.
