AUTONOMOUS COMPLEX FOR EXPRESS ESTIMATION OF DYNAMICS OF ELECTRIC ACTIVITY OF SOILS Russian patent published in 2006 - IPC G01N33/24 

FIELD: ecological monitoring and diagnostics of functional condition of soil types, possible use in agriculture, soil science and during performing of researching, land-surveying and other types of operations.

SUBSTANCE: autonomous complex for express-estimation of dynamics of electric activity of soils contains measuring probe, connected through block for transforming signals to block for their processing and indication, autonomous stabilized source of electric power for signals transformation block. Block for transformation of signals contains multiplexer, connected to controller, having control keyboard, through serially connected analog-digital converter, low frequencies filter, circuit for synchronization with controller, and also, connected thereto, energy-independent memory device, display and circuit for synchronization with block for indication and processing, containing microprocessor computing device and an indicator. Probe is made in form of dielectric cone with electric-conductive measuring rings positioned on it along circuit, aforementioned rings having electric outputs.

EFFECT: device makes it possible to increase precision of measurements of dynamics of electric activity of soils at different soil levels under real field conditions.
