Automatic Measurement Computation and Recording of Dielectric Constant and Loss Factor against Temperature
Edward B. Baker · Review of Scientific Instruments · 1951
An automatically computing and recording instrument for dielectric constant and dielectric loss as a function of temperature at any constant frequency from 50 cps to 600,000 cps is described. Sample curves are shown. Known magnification and zero shift are incorporated to cover the ranges of values encountered in most plastic materials. Automatic correction for and measurement of thermal expansion is incorporated.
