磁电式速度检波器是工程中常用的传感器，但受其固有频率的限制，不适于测量低频振动。本文详细研究了在检波器的输出端并联电容对检波器特性的影响，发现并联电容的效果相当于增加悬挂系统的当量质量和当量阻尼系数。这种做法的特点在于以损失高频段的灵敏度为代价，换来系统固有频率的降低和机械量程的扩大及耐冲击性能的提高，与此同时，低频段的信号强度并没有明显减弱。在此基础上，用电路网络对磁电式检波器的低频特性作进一步的校正，得到了惯性式特殊低频传感器。
Magnetoelectric speed detector is commonly used in engineering sensors, but by its natural frequency limit, not suitable for measuring low frequency vibration. In this paper, the effect of shunt capacitance on the detector characteristics at the output of the detector is studied in detail, and the effect of shunt capacitance is found to be equivalent to increasing the equivalent mass and equivalent damping coefficient of the suspension system. This approach is characterized by the loss of the sensitivity of the high frequency band in exchange for a reduction of the natural frequency of the system and the expansion of the mechanical range and the improvement of the impact resistance. At the same time, the signal strength in the low frequency band has not been significantly reduced. On this basis, the low frequency characteristic of the magnetoelectric detector is further corrected by the circuit network, and the inertial special low frequency sensor is obtained.
