摘要
WB系列霍尔电流传感器/变送器具有线性好、频带宽、响应快、过载能力强等优点。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。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。磁补偿式与直测式的区别在于其铁磁体上另加一平衡绕组,霍尔器件仅检测被测电流和平衡绕组中电流在铁磁体中所产生的磁电势的平衡状态。
WB series Hall current sensor/transducer possesses a lot of advantages as well as better linear, wider frequency band, faster response, and bigger over loading. 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. 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. The difference of the two modes is adding the secondary coil at the magnet of the closed-loop sensor. The Hall part measure the magnetism voltage difference state of the measured current and the secondary current.
