| Summary: | A high-precision calibration device was established for self-developed free frame wire high temperature strain gauges,a feasible calibration method was introduced,and some important parameters which affect the measuring results were determined. The change curves of sensitivity coefficient,thermal output,zero-drift and creep with temperature were obtained according to the calibration method,and a compensation model was proposed for strain measurement. Verification test results prove that the calibration method is feasible and correct and can be promoted to other forms of high temperature strain gauge parameter measurements. |
