Automated Mercury Dilatometer
Abstract
Task of reading and recording indications of mercury dilatometer simplified by automatic system. Volume change of sample under test converted into electrical signal. Device modified by addition of resistance wire to mercury column. Height of column read indirectly by measuring resistance between terminals. Signal suitable for strip-chart recording or other processing.
