查询词典 magnetic flux

Fluxgate sensors have the second harmonic voltage amplitude with the magnetic field strength is proportional to the adoption of second harmonic filter through phase-sensitive detector rectifier, to achieve full-wave rectifier, low-pass filter in through the phase-sensitive detector after the second harmonic into a smooth DC signal, on the one hand to the back of the circuit, on the one hand, the magnetic flux through the door to feedback regulation, the opposite magnetic field generated with the measured magnetic field, so that the work has always been zero fluxgate magnetic field, thus ensuring the most high-precision fluxgate.

磁通门传感器产生的二次谐波电压幅值与磁场强度成正比，二次谐波通过通过滤波器再通过相敏检波器整流，实现全波整流，在通过低通滤波器将相敏检波后的二次谐波转化成平滑的直流信号，一方面送到后面的电路进行，一方面通过反馈调节送到磁通门中，产生与被测磁场相反的磁场，使磁通门始终工作零磁场下，从而保证磁通门的最高精度。关键词：磁通门磁力仪，相敏检波器，磁场
