Abstract
This invention relates to improvements in weldable strain gages of the type comprising a strain-sensing filament mechanically coupled to a strain-deformable housing. In a preferred embodiment of the invention, the strain-sensing filament comprises a carbon strand.
Claims3
In a strain gage having a metallic, tubular strain-deformable housing member, a strain-responsive elongated filament the resistance of which varies in accordance with strains occurring longitudinally thereto, a mass of solid compactable electrical insulating material mechanically coupling said filament within said housing member for deformation in direct proportion to deformation of said housing member, and means connected to said filament capable of monitoring the resistance thereof, wherein said strain-responsive filament comprises a carbon strand.
