Abstract
We describe a useful method using a commercial linear variable differential transformer as a detector to characterize a piezoelectric ceramic tube as a displacer. Results show some inhomogeneity in the reduction of the voltage-to-displacement conversion of commercial piezoelectric tubes as a function of temperature from room to liquid-helium temperature.Keywords
