Pressure measurement cell for pressure sensor, has spacer ring including side closed by contact plate, and membrane including fastening edge protruding in direction of spacer ring, for retaining membrane at spacer ring

摘要

The cell (1) has a contact plate (10) on which a pressure chip (20) is arranged. A spacer ring (30) has a side that is closed by the contact plate in an axial direction, and another side that is by a membrane (40) in the axial direction. The membrane has a fastening edge (42) protruding in a direction of the spacer ring, for retaining the membrane at the spacer ring. The fastening edge and the membrane are provided at an angle of 90 degrees from each other. The fastening edge has a wide angular offset. The contact plate and the spacer ring are made of plastic. Independent claims are also included for the following: (1) a method for manufacturing a pressure measurement cell of a pressure sensor (2) a method for manufacturing a pressure sensor.
