电阻应变仪系电测非电量仪器之一专以测量工程结构杆件的应变问题,经过灵敏元件——“电阻应变片”的转换将应变的非电量,变成电阻的电量,用这仪器的测量的结果要比机械的光学的灵敏度与积确度都要高。电阻应变片,不但质量轻,标距小,惯性小,同时可长期测量与遥远测量,所以在实验室、工厂,工地都适用。本文仅介绍全部利用国产材料设计制造电阻应变仪的初步研究成果以及所发生的问题及经验。
Resistance strain gauges are non-electrical measuring instrument designed to measure one of the strains of structural engineering components of the strain, through the sensitive components - “resistance strain gauge” conversion will strain the non-electricity, into a resistance of electricity, using this instrument’s The result of the measurement is higher than the sensitivity and accuracy of the mechanical optics. Resistance strain gauge, not only light weight, gauge a small, small inertia, while long-term measurements and remote measurements, so in the laboratory, factories, construction sites are applicable. This article describes only all the use of domestic materials design and manufacture of resistance strain gauge preliminary research results and the problems and experience.
