Using single amorphous-core and double-winding as the sensitive element excited by multivibrator bridge, a kind of weak magnetic sensor with small size and high performance is developed.

其传感器是利用对磁场具有高灵敏度的钴基非晶态合金丝作为敏感材料，并采用单磁芯双绕组结构、多谐振荡桥励磁，它是一种体积小、性能高的新型磁场传感器。

The sensor is made up of original circuit, magnetic core, Hall part, secondary coil and magnifier. There are two work modes: direct measure mode and closed-loop mode.

其结构由原边电路、聚磁环、霍尔器件、次级线圈和放大电路等组成， 分直测式和磁补偿式两种工作方式。
