ABSTRACT:
A thin film strain gauge fabricated by depositing a first film of a high temperature insulating material upon a surface of an article to be tested, depositing both a thin film of a resistive material and a conducting lead in connection with each end of the resistive pattern upon the surface of the first film and overcoating the resistive strain gauge film and at least a portion of the conducting leads with a second film of high temperature insulating material to protect the strain gauge against corrosion and erosion in its operating environment.
