Abstract

PURPOSE:To perform stable measurement even if there are fluctuations in high- temperature environment or if there is a wind by installing fluctuation preventive walls on both flanks of two electrode plates. CONSTITUTION:The strain gauge measures the deformation of a body 10 to be measured within a distance G.L. between gauge marks by utilizing variation in the electric capacity between the two electrode plates 3. Further, a contactor 5 is fixed to the body 10 to be measured by spot welding. In this case, the electric capacity between the elctrode plates 3 varies with the temperature between the electrode plates 3 unless the G.L. varies. For the purpose, the fluctuation preventive walls 11 are fitted to a gauge base 1 on the flanks of the electrode plates 3 by spot welding 14. Consequently, the fluctuation preventive walls 11 prevent air from flowing 12 from by the gauge to reduce temperature variation, so the variation in electric capacity can be precluded without any variation in the strain of the body 10 to be measured. Namely, the strain is measured stably.
