Pressure sensor, and a method for mounting it

A pressure sensor element for mounting in a connecting element, comprising:

• a pressure transducer element for outputting a pressure-dependent signal;
• an isolator member, said isolator member having:
• an end face, an outer edge defined by said end face, a first opening in said end face, a second surface, a second opening in said second surface, a passage extending perpendicular to the mounting direction of the pressure sensor element from said first opening to said second opening, said pressure transducer element being connected to said passage through said second opening, a diaphragm which seals said first opening, said diaphragm extends radially outward beyond said outer edge of said end face, and a transmission medium in said passage for the purpose of transmitting the pressure present at said diaphragm to said pressure transducer element;
• and
• a pressure sensor element, wherein said diaphragm is connected to said end face along an inherently closed seam of said isolator member.

A pressure sensor arrangement, comprising:

• a pressure sensor element having:
• a pressure transducer;
• and an isolator member;
• said isolator member having an end face;
• and
• a connecting element defining a surface with an edge region and an opening extending from said surface, wherein:
• said pressure sensor element being fixed in said opening in such a way that said end face lies in a plane with said edge region and about said opening,
• a projecting region of said diaphragm is connected to said edge region along an inherently closed connecting seam about said opening.

A pressure sensor arrangement, comprising:

• a pressure transducer element for outputting a pressure-dependent signal;
• and an isolator member, said isolator member having:
• an end face, an outer edge defined by said end face, a first opening in said end face, a second surface, a second opening in said second surface, a passage extending from said first opening to said second opening, said pressure transducer element being connected to said passage through said second opening, a diaphragm fastened on said end face along an inherently closed seam, said diaphragm sealing said first opening, and a transmission medium in said passage for the purpose of transmitting the pressure present at said diaphragm to said pressure transducer element;
• a connecting element defining a surface and an opening extending from said surface of said connecting element for holding said pressure sensor element;
• and
• a diaphragm ring defining an inner edge region and an outer edge region, wherein:
• said pressure sensor element is fixed in said opening of said connecting element in such a way that said end face lies in a plane with said edge region and about said opening, and
• said inner edge region of said diaphragm ring is fastened on said end face by means of an inherently closed seam and said outer region being fastened on said surface of said connecting element by means of an inherently closed seam and about said opening.
