Abstract
An integrated seal and diaphragm member for a pressure sensor assembly may include a diaphragm portion and a seal portion integral with the diaphragm portion. In some cases, the integrated seal and diaphragm member includes one or more retention features integral with the diaphragm portion and/or the seal portion. In some cases, the seal portion may be thicker than the diaphragm portion and may extend around the perimeter of the diaphragm portion. In some instances, the seal portion may be configured to deform to form a seal with a pressure port of an external component or device without causing the diaphragm portion to move toward the pressure port in any significant way.
