MOISTURE METER (VERSIONS) Russian patent published in 2016 - IPC G01N22/04 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of measurement electrical equipment, namely, to a moisture meter to control the moisture of liquid and loose materials by the measurement of their dielectric permeability. The moisture meter comprises an electronic unit, a measurement cell and a primary converter of a high-frequency signal, formed by a metal base and a metal bar. The metal base is a bunker, a pipeline or a tray. An insulator is fixed on the first end of the bar, the bar by the second end is connected to the base. A metal body is fixed on the insulator, and inside the body a measurement cell is installed. A metal lug is installed on the base in the form of a sleeve with a hole in its bottom in the first version of the moisture meter. The body with the measurement cell is installed inside the sleeve and is pressed by a cover-fixator to the bottom of the sleeve. In the second version of the moisture meter on the base there are threaded pins, and the body with the measurement cell is pressed to the base by the plate with seating holes for the pins and is fixed by nuts.

EFFECT: increased the accuracy and stability of measurements under industrial conditions of operation, provision of the possibility to dismantle and install a moisture meter probe without changing of the settings.
