METER OF GRAIN MOISTURE Russian patent published in 1995 - IPC

FIELD: instruments. SUBSTANCE: device has primary transducer, which is made as capacitor-based detector, and measuring unit. Two switches, differentiating unit, inverter, two detectors of signal signs, two adders, sign-inverting and direct low-pass filters, unit for control of oscillator frequency, temperature correction unit are introduced into measuring unit. All described units are connected to one another in a described way and capacitor-based detector (measuring rod) has temperature detector. EFFECT: increased functional capabilities. 5 cl, 6 dwg
