| Abstract: | This paper introduced a new method to measure metal linear expansion coefficient,this method mainly uses the linear relations between the displacement and voltage of the Hall sensor to measure the micro displacement.It can be accurate to one thousandth of a micrometer,test results are demonstrated:This method has a simpler operation and higher precision. |
| Keywords: | metal linear expansion coefficient Hall sensor micro deformation |
