The clamp-on flexible Rogowski coil from Tianjin Grewin Technology Co., Ltd. is engineered for current measurement in tight spaces where traditional sensors cannot fit. Its flexible and lightweight design allows for quick installation without dismantling primary busbars or cables, making it ideal for retrofitting in crowded electrical panels. The coil’s open-circuited secondary eliminates saturation risks, ensuring safe operation even under overload conditions, while its excellent linearity supports precise measurements across a broad current range.
This Rogowski coil is part of a broader product line that includes split-core current transformers, toroidal CTs, and miniature CTs, all manufactured to meet IEC, RoHS, and CE standards as stated by the supplier. The flexible nature of the coil allows it to wrap around conductors of varying sizes, accommodating applications such as power quality monitoring, smart logging, and distributed measurement systems. Typical industry specifications for Rogowski coils include a measurement range of 10A to 5000A, a frequency response of 5Hz to 10kHz, and an accuracy of ±0.5% to ±1% of reading.
Industries such as utilities, renewable energy, and industrial automation commonly use these coils for non-invasive current monitoring in high-voltage or high-current environments. The ability to install the coil without breaking circuits reduces downtime and installation costs. Trade terms, including MOQ, packaging, and Incoterms, are not specified in the listing and should be confirmed directly with Tianjin Grewin Technology Co., Ltd.

Before placing an order, verify the Rogowski coil’s compatibility with your conductor sizes and current ranges, as these are critical for accurate measurements. Confirm whether the coil’s output signal requires external integration circuitry, and if so, whether the supplier provides this as part of the package. Additionally, request documentation such as calibration certificates or test reports to ensure the coil meets your accuracy requirements.
Logistics details, including lead time, Incoterms, and shipping methods, should be clarified with Tianjin Grewin Technology Co., Ltd. to ensure alignment with your project schedule. Packaging specifications are not listed, so inquire about protection during transit, particularly if the coils will be exposed to moisture or mechanical stress. Payment terms, including L/C or T/T, should also be agreed upon in advance to prevent delays in order processing.
Quality checks should include testing the coil’s linearity and phase shift error across its full measurement range, as these directly impact accuracy in power monitoring applications. Inspect the coil’s flexibility and durability, ensuring it can withstand repeated bending without degradation. Request compliance documentation for IEC, RoHS, and CE standards, and consider a pre-shipment inspection for bulk orders to verify adherence to specifications.
