Product Description

Rogowski Coil current sensors are designed for fast and easy installation on existing primary conductors or bus bars. The split design permits non-contact AC current or current pulse measurement without requiring that the primary conductor be taken offline and disconnected. This method provides for safe, easy, and portable measurement of current.

Since the sensor does not incorporate a magnetic core, magnetic core saturation is avoided, offering significant advantages over standard magnetic core current transformer products.

Frequently Asked Questions

Can this sensor be installed on a live conductor?
Yes, the split design allows for non-contact installation without taking the primary conductor offline or disconnecting it.
What is the advantage of a coreless design?
Because it does not have a magnetic core, the sensor avoids magnetic saturation, ensuring linearity and high accuracy across a wide current range.
What output signals are available?
We offer multiple options including 0-100mV (passive), and integrated outputs like 0-5Vac, 4-20mA, or 333mV.
Are different coil lengths available?
Yes, standard lengths include 210mm, 350mm, 420mm, and 510mm, catering to various bus bar and conductor sizes.
Is the sensor suitable for outdoor use?
The standard model is rated for indoor operation conditions with an operating temperature range of -20ºC to +60ºC.
Can I return the product if I change my mind?
As this is a customized product involving complex technical processes, it does not support returns or refunds once the order is confirmed.
