Determination of Absorption Properties of Separators in Lead-Acid Storage Batteries

Presented in this paper are the results of creation of radiophysical method for separators hydrophily definition. The method is based on determination of electrolyte volume content in separator from the value of microwave signal attenuation as a consequence of separator insertion into microwave transmission line. High accuracy is achieved using specific equipment implementation: bridge method and high stability of sounding radiation frequency provided by temperature-compensated semiconductor self-oscillator with high-Q reference resonators, and also due to special diodes interconnection, providing minimum modulation sensitivity.
