电阻应变片是测量应变的一种有效工具,是科研单位和生产部门一种有用的测量元件。它可以用在各种不同的金属、混凝土、砖、木材、橡胶、塑料等材料上。现在,电阻应变片的应用已经深入到宇宙航行、航空、原子能、机械、冶金、石油、仪器、建筑、水利、医学等各个工业部门和科学领域中。在我国,这种技术发展很快,应用很广,例如许多工业部门已经采用电子秤,在应力分析、应变测量、强度结构试验、振动测量和挡板流量计等方面都得到了应用。
Resistance strain gauges are an effective tool for measuring strain and are a useful measuring element for research institutes and production departments. It can be used in a variety of different metals, concrete, brick, wood, rubber, plastic and other materials. Nowadays, the application of strain gages has gone deep into various industrial sectors and scientific fields such as space navigation, aviation, atomic energy, machinery, metallurgy, petroleum, instrumentation, construction, water conservancy and medicine. In our country, this kind of technology develops rapidly and has a wide range of applications. For example, many industrial departments have adopted electronic scales and have applied them in stress analysis, strain measurement, strength structural test, vibration measurement and baffle flowmeter.
