Milan, the beating heart of Italy's industrial powerhouse, is undergoing a profound transformation. As Lombardy transitions toward Industry 4.0 and Smart Grid technology, the demand for high-precision current sensing has reached unprecedented levels. The High Frequency Rogowski Coil Sensor has emerged as the gold standard for engineers in Milan's automotive, aerospace, and energy sectors. Unlike traditional iron-core transformers, these air-cored sensors offer no magnetic saturation, providing exceptional linearity for high-speed transient analysis.
From the high-tech manufacturing plants in Rho-Fiera to the innovative data centers in the Settimo Milanese tech hub, high-frequency current measurement is critical. Our role as a premier Rogowski Coil sensor supplier in Milan ensures that local industries have access to sensors capable of capturing fast-changing currents in pulsed power systems, induction heating, and modern power electronics converters.
Our Rogowski coils are engineered for high-bandwidth measurement, essential for detecting high-order harmonics and transient spikes in Milan's complex electrical networks. With bandwidths extending into several megahertz, these sensors provide a level of detail that traditional CTs simply cannot match.
We specialize in providing integrated solutions. Whether you need a sensor for a specific power analyzer or a custom-formulated flexible loop for tight spacing in Milan’s urban electrical substations, our engineering team provides bespoke consultancy and manufacturing.
Adhering to IATF 16949 and ISO9001 standards, our production facilities ensure every sensor exported to Milan meets the highest European safety standards. Electrical safety and fault protection are at the core of our Rogowski coil designs.
Fujian Smrtr Technology Co., Ltd. Zentar®, is a leading global manufacturer of magnetic components for electrical safety and power measurement, established in 1993. With nearly 30 years of experience, we have become a trusted partner for industrial clients in Milan and beyond. Our operating facilities employ approximately 410 people, including a specialized R&D team led by professors and 20 senior engineers.
We provide comprehensive expertise in consulting, design, and manufacturing of current transformers, RCD fused connection units, and wireless energy monitors. Our infrastructure covers 40,000 square meters, equipped with automatic winding machines and precise testing equipment to ensure annual production capacities of 50 million magnetic components.
