| titleOfInvention | Device for testing and calibrating strain gauge in high-temperature environment |
| abstract | The invention discloses a device for testing and calibrating a strain gauge in a high-temperature environment, belongs to the technical field of high-temperature strain, and relates to a device for testing and calibrating the strain gauge in the high-temperature environment. The device consists of a power supply, a measuring system, a loading system, a supporting unit, a heating and heat insulation system and a calibration beam clamp assembly. The measuring system consists of a temperature sensor, a displacement sensor fixing frame, a temperature sensor fixing frame, a computer and a digital instrument; the loading system consists of a motor driver, a motor actuator, a linear stepping motor and a ceramic contact rod; the heating system is formed by connecting a gas tank, a gas pipe and a heating source in sequence. The device accurately controls the heating temperature of the strain gauge, and controls and measures the micro strain generated by the strain gauge with high precision. Accurately detecting and calibrating performance parameters such as strain sensitive coefficient, drift rate, creep lag and the like of the strain gauge; the method has the characteristics of simple operation, high testing precision, good repeatability and wide temperature change range. |
