Abstract
Methods, apparatus, and systems are provided for sensing pressure. One example apparatus includes a housing having a first port, a chamber disposed in the housing and having a second port, wherein the second port is coupled to the first port such that a volume inside the chamber is in fluid communication with an environment external to the housing, and a pressure sensor assembly at least partially disposed in the chamber and configured to sense a pressure of a fluid in the chamber. The chamber may be mechanically coupled to the housing via a portion of an exterior surface of the chamber such that a pressure response of the pressure sensor assembly is independent of extraneous loading on the housing.
