FIELD: measuring equipment. SUBSTANCE: elastic member of tensoresistor device designed for measuring deformation is made of two thin-walled rings connected in series to each other along their axis of symmetry. Rings are coupled by assembly which presets normalized value of parameter being measured. This assembly and assemblies which couple elastic member to construction under test are provided with base holes for mounting the calibration appliance on device. EFFECT: wider range and higher accuracy of measurement; calibration of device directly on construction under test. 7 dwg
