用于电网监控、过程控制和电力监控的EtherCAT终端
透明能量监测
透明的能源监测既减少了机器的停顿，也减少了由于工厂可用的原因而使相应部件尺寸过大的必要性。此外还有预防性维护，***终大大提高了生产效率。随着其综合功率测量的组合，贝克霍夫简化了能源管理，同时优化了机器和工厂的可用性。由于连续的、系统集成的功率测量，可以快速检测出偏离标准状态的偏差，从而实现快速干预。例如，机器不断增加的电流消耗可能意味着轴承磨损。另一方面，当前消费减少可能意味着质量问题，需要在早期阶段加以纠正。通过监测电源，错误行为可归因于电网中可能出现的相位故障。降低了反应速度，避免了可能的停机时间。
所有应用领域的可伸缩性
可伸缩性是贝克霍夫的一项原则：这也适用于EtherCAT电力测量终端，它涵盖了从简单的网格监控到所有应用领域的电力监控的应用程序。它们在测量精度、测量速度、测量值和内部计算值方面根据不同的性能等级进行衡量。Bechoff EtherCAT I/O为此提供了一系列的EtherCAT终端，在价格和性能方面都具有很高的可伸缩性。
综合系统组合
除了EtherCAT终端，功率测量组合还包括作为可靠功率传感器的电流互感器与I/O的***佳兼容性。我们的TwinCAT自动化软件的功率监测软件库也围绕功率测量。控制柜内有适当的附件，以增加安全。这样就形成了一个完整的功率测量组合，这样所有的组件都可以从一个单一的源中获得。

***简单诊断的电能质量因数
从纯电网监控到过程控制，到高端电力监控，在机器环境和能源经济中，在能源管理方面有各种各样的要求。EL34xx和EL37x3能源和功率测量终端设置了不同的焦点，因此是为广泛的应用而设计的。
从简单的阈值检查电压，频率和相位，输出警告和状态位与beplay体育注册登录 和能源管理项目与EL3423。EL3443和EL 3453也是三相电网高性能应用的合适终端，它们在内部对测量的电流和电压值进行预处理，从而为控制器提供多达600个数值，用于广泛的电网分析和能源管理。EL3773和EL 3783可用于具有过采样功能的电力监控。这允许同时测量电流和电压，在所有通道上以高达10 KSPS的速度同时测量电流和电压，以便进行时间上的***状态检测。
利用EL3446和EL3443相结合，可以实现分布式功率测量，从而可以通过空间分离的电压和电流测量来计算有效功率值。EL 3446纯电流测量终端可按所需的频率定位在栅极中。为了计算实际的功率数据，所需的电压值从EL 3443三相功率测量终端发送，该终端只在每个电网中安装一次。这种分布式功率测量的概念--只有一个EL3443和任意数量的EL3446s--将硬件和安装费用降到***低。
贝克霍夫的能源和功率测量组合也具有中等电压水平的产品。中压电平中的电压可以通过100 V或110 V输出的标准电压变压器简单地连接到我们的测量范围为130 V的交流终端。
在某些应用中，如果为了质量原因而获得测量行为和不确定度的知识，就必须对终端进行校准。我们也可以通过校准的功率测量终端来满足这些要求。
