摘要:

本文对磁饱和式磷力仪探头的灵敏性提出了一种新的激励方法.用对称的三角波激励可以减小测量线圈输出的二次谐波电压的绝对误差和相对误差,而且克服了磁饱和磁力仪的测量误差随场强增加而高挂增大这一弱点。

Abstract:

A new exciting method of the sensor in the saturated magnetemeter’s is presented n this paper,The fractional error and the absolute error of second harmonic volt in measuring coil can be decreased by employing symmetric trigonometric wave to excite it. And the saturated magnetometer can be used to survey power magnetic field strength.
