Abstract

A pressure sensor includes a housing that includes an interior surface and an axially symmetric liner disposed along the interior surface of the housing, where the liner includes an interior surface and an exterior surface. The pressure sensor further includes a sensing member that includes an interior surface and an exterior surface, where the interior surface of the sensing member is adjacent to the exterior surface of the liner, and the sensing member is configured to expand with the liner. The pressure sensor further includes a strain gauge affixed to the exterior surface of the sensing member.
