Abstract:Based on the properties of the density and the expansion coefficient of liquid,the experiment of liquid expansion coefficient is designed by using silicon force sensor. Through measuring the output voltage of different temperture,the expansion coefficients of liquid are measured,and the electrical measurement of force which is a non-electric parameter is realized.
Keywords:force sensor  liquid  expansion coefficient
