Pressure sensor membrane fastening arrangement comprises a circular membrane with an annular bead whose circular section matches the circular section of grooves in enclosing sensor housing and insert sections

摘要

Membrane fastening arrangement for a pressure sensor is formed from a housing, an insert and a circular membrane (40). Housing and insert have aligned grooves in their matching end surfaces. The membrane has an annular bead (41) with a circular cross section that is inserted between the housing and insert. The grooves have rounded sections whose radii match that of the annular bead circular cross section.
