直测式是将霍尔器件置于具有线圈绕组或直穿母线的环型铁磁体气隙中，测出气隙里的磁压降，即为被测电流。

The direct measure mode is that Hall part is set into the interspace of loop winding or magnet coil, then the magnetism voltage difference or the current is measured.

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。

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.
