Abstract
Systems and methods for isolated sensor device protection are provided. In one embodiment, an isolated sensor device comprises: a housing having an isolation chamber; an isolator sealed within the isolation chamber; an inertial sensor assembly sealed within the isolation chamber, the inertial sensor assembly coupled to an inner surface of the isolation chamber by the isolator; and at least one progressive impact interface applied to a periphery of the inertial sensor assembly, wherein the at least one progressive impact interface extends outward from the inertial sensor assembly towards the inner surface.
Claims18
An isolated sensor device, the device comprising:
- a housing having an isolation chamber;
- an isolator sealed within the isolation chamber
- an inertial sensor assembly sealed within the isolation chamber, the inertial sensor assembly coupled to an inner surface of the isolation chamber by the isolator;
- at least one progressive impact interface applied to a periphery of the inertial sensor assembly, wherein the at least one progressive impact interface extends outward from the inertial sensor assembly towards the inner surface;
- wherein the at least one progressive impact interface comprises an angular extended lip that extends both radially and axially away from the inertial sensor assembly and towards the inner surface.
