... and technique of determining moisture content with a penetrometer that can measure the dielectric constant (specific inductive capacitance) of soils. Effects of various factors, such as salt content of water, on the measured parameter are discussed with special reference to frequency of the measuring bridge...

...Martin Feldman; Dooyoung Hah; Khalil Hanifa; Zhongjie Zhang A combined dynamic cone penetrometer and capacitive soil moisture meter is reported. A novel electrode configuration utilizing a shield electrode increases the effective measurement diameter. A readout circuit is implemented...

... without a truck-mounted rig and that the data collected can be used to map deposit-scale heterogeneities in the wetland soil type. wetlands piezocone penetrometer in-situ testing References ASTM , 1994 , Test Method for Deep Quasi-static Cone and Friction Penetration Tests in Soil (D 3441...

...G Singh; BM Das; MK Chong Reliable in situ testing during soil exploration is of great help to geotechnical engineers in design considerations. This paper describes the theory and the laboratory test results for determination of the density of a sand with a quasi-static penetrometer by measuring...
