MAGNETOMETER (EMBODIMENTS) Russian patent published in 1997 - IPC

FIELD: measuring technology for magnetometric prospecting. SUBSTANCE: magnetometer in the first embodiment has an additional single- component magnetic sensor and an additional amplifier- transducer whose first input and first output are connected to the first output and first input of the additional sensor, respectively. Second inputs of the additional amplifier- transducer and the additional sensor are connected to the outputs of a variable-emf generator. Second outputs of both amplifier-transducers are connected to the inputs of a summator whose output is connected to a recorder. Magnetic axes of both sensors are collinear, the magnetic axis of the main sensor positioned in the frame plane of an anisator magnetic screen. Unlike its first embodiment, a magnetometer in the second embodiment has the second output of the additional amplifier-transducer connected to the recorder and the second output of the main sensor to the first input of the additional sensor. Magnetic axes of both sensors are collinear, the magnetic axis of the main sensor placed in the frame plane of the anisator magnetic screen. EFFECT: improved design. 3 cl, 4 dwg
