Abstract
A pressure measuring transducer includes a pressure measuring cell; a measuring cell housing having an annular axial abutment surface, which surrounds an opening; a sealing ring; and a ring of angular cross section for positioning the pressure measuring cell and the sealing ring in the measuring cell chamber. The ring of angular cross section includes at least a first component of a form-retaining material and at least a second component of an elastic material, wherein the at least one form-retaining component forms the radial shoulder and extends in the axial direction into the annular gap, and the second component is connected with the first component and extends in the annular gap at least sectionally radially between the lateral surface of the pressure measuring cell and the wall of the measuring cell chamber.
