Wide Range Strain Technology Research In Wide Temperature Range Environment

In the defense, building, metallurgy, materials, and other countries major engineering field, strain sensor has a wide application. Strain sensor can accurately measure force and strain or some other physical quantity, which is a very important measurement instruments.In order to more accurately calibrate and correct the sensor, this paper introduces a kind of feasible solution. And complete principle analysis, general design, standard strain beam design, and mechanical and electric control system design of the calibration system. What’s more, successful research and develop a set of strain sensor calibration device in wide temperature range environment. According to a lot of experimental data, the performance of this device is reliable. And systematically analyze the uncertainty of device.
