Paper Abstract

Fused quartz is characterized by extreme low coefficient of linear expansion , small elastic hysteresis and good stability. Thus , it is an ideal material for sensor. A capacitive inclination sensor i s presented in this paper ,whose sensing element is made of fused quartz and fixed plates are made of invar. So it has very small temperature shift. The sensor uses differential structure to reduce non-linearity and improve sensitivity. Its mass block is supported by a flexibility bridge. Therefore , friction, wearing and moving due to the gap in supports are avoided. The design work and experiment results are given in the paper.
