The apparent strain of temperature self-compensated strain gages at cryogenic temperature is presented. By joining the international round robin test on electrical strain gages at cryogenic temperatures, apparent strain curves of up to the fourth order with respect to the temperature are obtained with different strain gages and different materials. The liquid nitrogen and the liquid helium are employed to get the cryogenic environment. The results can be effectively utilized to determine the real strains by mechanical loading at cryogenic temperature. This paper also describes the optimal selection of strain gages and test materials for the use of strain gages at cryogenic temperature.
