Description
technical field [0001] The invention relates to the technical field of high-temperature strain, in particular to an electric measuring device for high-temperature strain gauge parameters from room temperature to 1200°C. technical background [0002] Strain measurement of industrial equipment under high temperature conditions is an important part of the test system. At present, the design and use parameters of adhesive strain gauges are based on the national standard "GB-T 13992-2010". Since this standard replaced the "GB-T 13992 1992" implemented in 1992, and there is no reference basis for the calibration method of strain gauges, there is no specific national standard for the commonly used adhesive resistance strain gauge measurement devices and methods. There are few people involved in the field of strain calibration devices. [0003] Existing strain gauge calibration devices generally work at room temperature. At present, there are a small number of high-temperature str...
