Pressure sensor for sealed containers
First Claim
Patent Images
1. A pressure sensor suitable for detecting a pressure change inside a container, said sensor comprising:
- a sealed deformable vessel disposed inside the container;
a deformation indicator mounted to said vessel which provides an indication of vessel deformation which is detectable external to the container; and
a detector disposed outside of the container, wherein a change in pressure inside the container deforms said vessel, and said detector detects the indication provided by said deformation indicator of the vessel deformation, wherein said deformation indicator is a magnet mounted to said vessel located at a distance away from an exterior surface of said container, and wherein a pressure change in said container causes deformation of said vessel changing said distance of said magnet away from said container surface.

Abstract
A magnetic pressure sensor for sensing a pressure change inside a sealed container. The sensor includes a sealed deformable vessel having a first end attachable to an interior surface of the sealed container, and a second end. A magnet mounted to the vessel second end defining a distance away from the container surface provides an externally detectable magnetic field. A pressure change inside the sealed container causes deformation of the vessel changing the distance of the magnet away from the container surface, and thus the detectable intensity of the magnetic field.

17. A magnetic pressure sensor comprising:
-
a sealed deformable vessel having a first end attachable to an interior surface of a container, and a second end which moves when said vessels deforms due to a pressure change in said vessel; and
a magnet having, a magnetic field detectable from outside of the container, said magnet being mounted to said vessel second end located at a distance away from said container surface, wherein a pressure change in said container causes deformation of said vessel changing said distance of said magnet away from said container surface and the intensity of the magnetic field detectable from outside of the container. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
