在重工业和加工业监测大直流电流

很多工业领域的基本生产和加工过程都需要使用大直流电流。例如，用于金属提取或化学品生产的电解工艺、金属镀层工艺或电弧焊技术。除此之外，直流电机易于控制，并且在所有转速范围内都具有恒定的转矩，因此，在许多工业应用中都是首选。

直流工业 - 供电领域的模式转换

从中期来看，增加对工业设备的直流供电也将发挥重要作用。与现有的交流供电相比，直流电网可大幅简化系统并提高效率，因此 Open DC Alliance (ODCA) 致力于大范围推行直流供电。 ODCA 的创始成员包括 Knick，该组织发布了在工业设备中采用直流电网的完整系统概念。发展仍处于起步阶段，但由于无可争议的巨大经济优势，未来具有相当大的潜力。作为工业直流应用的领先测量技术专家，我们密切关注这一发展。我们拥有广泛的专业知识和制造深度，能够针对该领域的严苛测量技术挑战开发理想的解决方案。

为何选择 Knick?
如果要在恶劣条件下安全测量高直流电压和大电流，Knick 高隔离性变送器无疑是不二之选。高压变送器的增益误差小于测量值的 0.3%，能采集高达 4500 V DC 的电压或者高达 20000 A 的电流（通过分流电阻），并作为 4...20 mA 标准信号输出。由于分流变送器标配 3 端口隔离并且有稳定的共模特性，因此传输距离长、测量点与控制中心之间的高电位差以及强烈的 EMC 影响都不是信号传输的干扰源。
