HERMETICALLY SEALED HIGH TEMPERATURE STRAIN GAGE ' ' '' ABSTRACT OF THE DISCLOSURE A hermetically sealed strain gage for measuring strains of high temperature parts comprises an attachment shim plate which is adapted to be secured to the part to be measured. A first înner cylinder member has one end sealing- ly secured to the shim plate and a second outer cylindrical member is disposed over the first member and has an end which is also sealingly secured to the shim plate. The outer wall of the inner member is spaced from the inner wall of the outer member and first and second spaced apart capacitor plates are arranged at substantially diametrical- ly opposite sides of the inner cylinder member in spaced relationship, each other. A cover plate is sealingly secured to the opposite ends of the inner and outer cylinder members and closes the space between these members. Capacitors are connected electrically outwardly through conductors in a lead wire and the changes of the capacitance caused by the shift in positions of the plates due to the strain pro- vide some indication of the strain involved, Other sensing means such as photoelectric arrangements may be used to sense the variation in position of the capacitor plates.
