A pressure sensor includes a supporting member, a membrane and a jacket that define a sensor space in which a measuring element is arranged. A liquid fills the sensor space and surrounds the measuring element.

Sensor

The invention relates to a method for producing an acceleration sensor having a housing (), which has a cylindrical or cubic basic shape, having at least one internal support () and having a sensor element () arranged thereon. According to the invention a sensor element () comprising a main body () having a head part () and an end face () opposing said head part () is premounted, by surrounding the head part () with at least one piezoelectric measuring element (), a seismic composition () and a clamping ring (). The end face () is subsequently positioned on the inner support () of the housing () in contact therewith to form a contact zone () between the end face () and the support (). Finally, the sensor element () is welded in this contact zone () to the housing (). The invention further relates to an acceleration sensor produced using said method.

Method for producing an acceleration sensor

A high-pressure sensor comprises an inner part, a housing and a sealing system located between the inner part and the housing for sealing the high-pressure sensor. The inner part has a shaft having an end face resting, by means of a clamping force, at least along a sealing line on a support surface at a projection on the housing. Each of the projection and the shaft has an inner surface and an outer surface. The support surface is arranged in an acute angle with respect to the inner surface of the projection. The shaft by means of the clamping force is supported on the housing along a support line whereby the sealing effect can be increased with increasing pressure.
