Insulated structure for an appliance
An insulated structure for an appliance includes a plurality of walls, a cavity defined by the plurality of walls, and an aperture defined by one of the plurality of walls. The aperture is employed in evacuating the cavity to establish a less-than-atmospheric pressure within the cavity. A base structure is coupled to an interior surface of the one of the plurality of walls that defines the aperture. The base structure is aligned with the aperture. A pressure sensor is received by the base structure. The base structure and the pressure sensor together define a pressure-sensing assembly.
