Flexible Rogowski Coils CT RNC Series
ARNOWA Flex Series is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. NRC coils are available in different sizes and can be supplied according to customer’s design; therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/or weight.
Product Description
