发明名称 MICROWAVE METER OF DIELECTRIC MATERIAL MOISTURE
摘要 The gauge is applied in agriculture, construction, industry and measurement equipment. It has a very fast action, higher accuracy and reduced dependency on the compactness of the material. The gauge contains three directed diverters (1,2,5), a hyper high-frequency generator (3), an applicator (4) with a emitting (7) and receiving (8) antenna and a measured material (9) between them, detectors (10,6) of, respectively, falling and passing through the material (9) voltage, a logarithmic divider (11), navigable attenuator (13) and a leg regulator (14), a tripler (15), a detector (15), a transformator of voltage under current (17), a summator (19), a divider (20), a differential amplifier (34), support sources (21,24), and outlets (12,18,22,25), respectively of signals of attenuation, leg displacement and humidity.<IMAGE>
