Abstract: A method of installing foil type electrical strain gages wherein adhesive is applied and the gage pressed about is periphery to provide a fluid pressure seal. The gage and the structure are then pressurized directly in a fluid pressure vessel chamber and the pressure maintained while the vessel is heated to provide full curing of the adhesive.

Abstract: A strain gage type load sensor having a central disc with a plurality of radially outwardly extending spokes each having the ends thereof flexurally attached to an outer annular reaction portion by means of a pair of oppositely directed beams extending from the spokes at right angles thereto for flexually suspending the central disc from the annular portion. A plurality of upstanding posts supporting a common block. The beams and posts are strain gaged for sensing bending loads. In another embodiment, two central discs are stacked axially with each suspended by connection of the spokes to the annular reaction portion. A first group of strain gages is disposed at mid-radius of the spokes for sensing radial tension and compression strains in the spokes. A second group strain gages is disposed at the inner and outer spoke ends for sensing bending strains in the spokes.
