应变测量技术广泛应用在各工业部门。目前,我国使用的应变片,当环境温度改变时,会严重影响测量精度,必须使用补偿片进行温度补偿,才能正常工作。近年来,国外出现了能自动补偿温度影响的应变片,制造这种应变片的康铜箔,其电阻温度系数要求与被测试材料的线膨胀系数相匹配,在室
Strain measurement technology is widely used in various industrial sectors. At present, the strain gauges used in our country, when the ambient temperature changes, will seriously affect the measurement accuracy, and must be compensated by the temperature compensation plate, in order to work properly. In recent years, foreign countries have appeared to automatically compensate for the temperature of the strain gauge, the manufacture of such strain gauge Kang Copper foil, the resistance temperature coefficient of the material under test with the linear expansion coefficient to match the room
