事实上，除了用于控制医学成像系统的梯度放大器上电流以外，HPCT同样适用于其他需要高精度测量的场合，如电流调节电源内的反馈测量、试验台电源分析校准设备以及实验室与计量仪器的电流测量。
目前，该类传感器的工作温度范围相对狭窄（一般为+10C 至+50C）。LEM确信以后会证明，这项用于发展HPCT传感器的技术对MRI扫描前景的意义与霍尔效应传感器对它的推出的意义一样重大，还会拓展到许多至今尚未预料到的应用领域。

优佩斯蓄电池UPS电源在正常使用情况下
主机的维护工作很少，主要是防尘和定期除尘。特别是气候干燥的地区，空气中的灰粒较多，机内的风机会将灰尘带入机内沉积、当遇空气潮湿时会引起主机控制紊乱造成主机工作失常，并发生不准确告警，大量灰尘也会造成器件散热不好。一般每季度应清洁一次。就是在除尘时，检查各连接件和插接件有无松动和接触不牢的情况。储能电池组目前都采用了免维护电池，但这只是免除了以往的测比、配比、定时添加蒸馏水的工作。但外因工作状态对电池的影响并没有改变，不正常工作状态对电池造成的影响没有变，这部分的维护检修工作仍是非常重要的，UPS电源系统的大量维修检修工作主要在电池部分，储能电池的工作全部是在浮充状态，在这种情况下至少应每年进行一次放电。放电前应先对电池组进行均衡充电，以达全组电池的均衡。要清楚放电前电池组已存在的落后电池。放电过程中如有一只达到放电终止电压时，应停止放电，继续放电先消除落后电池后再放。核对性放电，不是追求放出容量的百分之多少，而是要关注发现和处理落后电池，经对落后电池处理后再作核对性放电实验。这样可防止事故，以免放电中落后电池恶化为反极电池

UPS power supply of ubers battery under normal use
The maintenance work of the main engine is very little, mainlydust-proof and regular dust removal. Especially in the dry climatearea, there are many dust particles in the air. The wind in themachine will bring dust into the machine for deposition. When theair is wet, it will cause the control disorder of the main machine,cause the main machine to work abnormally, and give inaccuratealarm. A large amount of dust will also cause the poor heatdissipation of the device. Generally, it should be cleaned once aquarter. Secondly, when dedusting, check whether the connectors andconnectors are loose or not. At present, the energy storagebatteries all use maintenance free batteries, but this only avoidsthe previous work of measuring ratio, proportion and addingdistilled water regularly. However, the impact of external workingconditions on the battery has not changed, and the impact ofabnormal working conditions on the battery has not changed. Thispart of maintenance and repair work is still very important. Alarge number of maintenance and repair work of UPS power supplysystem is mainly in the battery part, and the work of energystorage battery is all in the floating charge state. In this case,the battery should be discharged at least once a year. Beforedischarging, the battery pack should be charged evenly to achievethe balance of the whole battery pack. It is necessary to know thebackward battery existing in the battery pack before discharging.In the discharge process, if one of them reaches the dischargetermination voltage, the discharge shall be stopped, and thebackward battery shall be eliminated before discharging. Checkdischarge is not the first to pursue the percentage of dischargecapacity, but to focus on the discovery and treatment of backwardbatteries, after the treatment of backward batteries, checkdischarge experiments should be carried out. In this way, accidentscan be prevented, so as to prevent the backward battery fromdeteriorating into reverse battery during discharge

如图1所示，这种传感器由一个用于产生磁场的载流导体组成。磁场用一个开有气隙的磁芯聚磁。气隙内的一个霍尔元件用于感应磁通密度。采用控制电流和差分放大，其组件通常集成在传感器内。在用于产生磁路的材料的磁滞回线（B-Hloop）的线性区内，磁通密度B始终与初级电流Ip成正比，霍尔电压VH与磁通密度B成正比。霍尔元件的输出与初级电流及失调霍尔电压Vo成正比。
环霍尔效应传感器工作原理
开环传感器可以测量直流、交流和复杂电流波形，还提供电流隔离。正如上文提及的，其优点是成本低、体积小、功耗低。它们在测量大电流（>300A）方面尤其有优势。开环传感器有一定局限性，例如磁路中的磁损耗导致的响应时间长及带宽不足、与温度相关的增益漂移相对较大。
闭环传感器，也叫霍尔效应补偿式或“零磁通式”传感器，它利用霍尔元件电压在次级线圈中产生一个补偿电流，从而使总磁通量等于零（图2）。换而言之，次级电流Is产生的磁通量与初级电流产生的磁通量完全相同，方向
闭环霍尔效应电流传感器工作原理
在零磁通条件下运行霍尔元件消除随温度变化的增益漂移，这种结构还具备一个好处，就是次级绕组在较高频率下起电流变压器的作用，这样就显著扩大了带宽并缩短了传感器的响应时间。
当磁通量等于零时，磁势（安培匝数）等于零，相应的，次级电流Is是初级电流Ip的映射。闭环传感器的优点包括非常高的精度和良好的线性度，快速响应时间，主要不足是次级电源电流消耗大，因为它必须提供补偿电流和偏置电流。
在技术规格要求更严格的特定应用场合，例如超低非线性误差、低噪或非常低的与温度相关的失调漂移等，这时霍尔效应电流传感器不再适用。为了满足这些要求，LEM研发了双轴磁通门闭环传感器（HPCT），它可以提供精度和稳定性均非常高的直流和交流电流测量，消除初级端注入的噪声。
图3详细说明了其工作原理。该传感器包括一个由三个磁芯（C1、C2和C3,）以及初级绕组（Wp1）和次级绕组（Ws1 -Ws4）组成的电流测量头，如图所示。通过将次级电流Ic注入次级绕组Ws2中实现闭环补偿。Ws2后半段线圈与3个磁芯进行磁耦合，并与测量电阻Rm串联，从而产生一个输出电压。
HPCT传感器工作原理
对于较高频率范围，次级电流由两个次级线圈（Ws1和Ws2）之间产生的变压器效应产生。对于较低频率范围（包括直流），传感器起闭环磁通门传感器的作用，此时绕组Ws3和Ws4用作磁通门感应线圈。
由于磁通门技术已经普及了一段时间，LEM可以采用这种技术并加以改良。终研发的传感器精度非常高，温度失调漂移非常低，时间稳定性非常高。的线性度、超低的输出噪声提高了HPCT的精度和分辨率，而超大测量带宽（直流到200kHz，-3dB）确保了该传感器广泛的应用领域。
