Abstract:
A pressure measurement cell is disclosed including a base body, substantially cylindrical at least in sections, a measuring membrane joined to the base body in a pressure-tight manner along a perimeter joint to form a measurement chamber between the base body and the measuring membrane, and a joining material that joins the perimeter joint between the base body and the measuring membrane. The base body and/or the measuring membrane have/has a stepped recess into which the joining material is at least partially disposed, the stepped recess structured to yield a minimum distance between the base body and the measuring membrane.
