应变传感器是国家极为需要的一种精密测量元件,它是藉助于弹性元件的电阻应变原理来测量各种非电量的参数——各种械机的位移、液体(气体)的压力、机械负载的拉(压)力、重量、扭矩、速度和加速度等。它广泛地用于机器制造、航空、冶金、农机、建工的生产中,已成为工业领域中主要的测量工具和固定的自动化元件。应变传感器一般由敏感元件(应变元件)、受力机构、保护外壳和插头等十余个另件组成。技术关键在于应变元件的加工工艺与应变计的粘贴技术比较复
Strain sensor is a kind of precision measurement element that is extremely needed in the country. It is based on the principle of resistance strain of elastic elements to measure various non-electricity parameters—displacement of various mechanical devices, pressure of liquid (gas), and mechanical load. Pull (pressure) force, weight, torque, speed and acceleration. It is widely used in the production of machinery, aerospace, metallurgy, agricultural machinery, and construction. It has become a major measurement tool and a fixed automation component in the industrial field. Strain sensors generally consist of more than ten pieces of sensitive components (strain elements), force mechanisms, protective housings, and plugs. The key to the technology lies in the comparison of the processing technology of the strain element and the paste technology of the strain gauge.
