摘要
利用磁电式速度计实现超低频振动传感器的方法,通过串联式校正电路,在保持最佳阻尼同时,使可测最低频率降至0.5Hz以下,经实际应用,受到良好的效果。重点对该超低频振动传感器的校正电路、工作原理、传递函数及校正前、后输出特性的差异进行了系统分析与阐述。
A measure of the lowest frequency is less than 0.5Hz by the method for ultra low frequency vibration sensor using magnetoelectric dromometer on the adjustable series circuit while retaining the best damp. The practical application of it shows a good result. The adjusting circuit, operating principle, transfer function, difference of characteristic adjusting before and after are analyzed and expounded.
