Ultraflex Current Sensor – IC-4AAALG6000

UltraFlex is a current sensor with an active part (Rogowski coil) characterized by a robust and reliable structure that allows the measurement of high currents (up to 6000A ) in the most demanding positions, thanks to the 600mm cord . Since they are not subject to magnetic saturation phenomena, they offer a very high linearity , a low phase shift and a wide measurement range .

UltraFlex can be used on all analyzers of the latest generation NanoVIP family (production from 2015 onwards with automatic recognition of amperometric clamps) with the exception of the DS model which can only mount the DC clamp.
For older NanoVIP analyzers (without clamp recognition) suitable adapters are available which allow their use in any case.
