MICROWAVE DEVICE FOR SOIL MOISTURE MEASURING Russian patent published in 2018 - IPC G01N22/04 

FIELD: measuring equipment.

SUBSTANCE: invention can be used in agriculture to study physical and mechanical properties of soil, in particular soil moisture. In the housing (1) of the microwave device, the power unit of the radiator (2) is placed, the microwave radiator (3) contains a resonator chamber (4) and is connected through a dielectric membrane (5) to the working chamber (7), forming a hermetic waveguide connecting with a microwave detector (8) measuring the intensity of the microwave radiation passed through the soil sample being tested. In this case, a test sample of soil enclosed in a dielectric tank (6) is installed in the working chamber (7) via the access window (11). The microwave detector (8) is connected via a data processing unit (9) to the soil moisture indication panel (10). The device is controlled by the radiator control panel (12) installed on the housing (1). The device is equipped with a global positioning module (13), which determines the coordinates of the moisture measurement points, which is connected to the data processing unit (9) and is installed in the housing. The data processing unit (9) receives signals from the microwave detector (8), the global positioning module (13), and outputs the results to the soil moisture indication panel (10). The increase in the reliability and accuracy of the moisture measurement results is a technical result of the invention.

EFFECT: device allows obtaining measurement results in relation to the coordinates of the sampling points of the soil, the device is universal for working with any types and compositions of soils.
