【 摘 要 】

The effect of design geometry on the output voltage, linearity and sensitivity of linear variable differential transformers (LVDTs) is presented. The effect of varying six geometric design parameters, including primary coil length, secondary coil length, inner and outer coil radii, and the length and radius of the core, on the transfer characteristics of LVDT is investigated using Finite element simulations. Output voltage vs. core displacement figures are used to determine the effect of the parameters investigated on the stroke and sensitivity.
