APPARATUS FOR DETECTING OBJECT AND/OR OBJECT CHARACTERISTICS OR ITS COMPONENTS, PREFERABLY FOR AGRICULTURAL OBJECTS Russian patent published in 1996 - IPC

FIELD: agricultural and agricultural product processing equipment. SUBSTANCE: apparatus has current conductive member connected with common screen and positioned in flush with or projecting in end spaces between dielectric members encircling first and second electrodes of capacity detector. Electrodes are connected with electromagnetic vibration generator and electromagnetic vibration amplifier. It allows insensitivity zone to be defined adjacent to apparatus. Apparatus is further provided with initial condition estimation device having unit for detecting absence of material under control within control zone and material quantitative characteristics control unit connected with material type and properties estimation unit, which is connected with characteristic linearization unit of apparatus. EFFECT: increased efficiency, wider operational capabilities by sectional construction of electrodes and two frequency measurements and enhanced reliability in operation. 8 cl, 20 dwg
