Patent ID: 8505365

Claim:
An apparatus for measuring pressure comprising: a housing having a housing wall; an actuator having a shaft extending along an axial direction from a first end of the actuator to a second end of the actuator, the actuator configured to be pressure sealed to the housing wall, in pressure communication with a volume enclosed by the housing wall, wherein the volume includes a pressure chamber having a chamber wall comprising at least a portion of a deformable member configured to be displaced at least partially in the axial direction upon a change in pressure in the pressure chamber, wherein the volume has a measurable pressure adjacent the first end of the actuator, wherein the actuator is secured to the deformable member adjacent the first end of the actuator, wherein the actuator is configured to be displaced at least partially in the axial direction upon a change in pressure in the volume, and wherein the actuator is configured to transfer axial motion from the deformable member to the shaft; the shaft having a magnetically encoded target configured to be detected by a static sensor by detecting axial displacement of the magnetically encoded target relative to the static sensor upon the change in pressure in the volume.
