Rogowski current sensor for currents up to 6000A and 600mm coil length ...
FLEXIBLE, STRONG WITH A WIDE RANGE OF MEASUREMENT UP TO HIGH CURRENTS
- Can be used on NanoVIP® family analyzers without the need for external power supply or amplification.
- Cord only 8,0 mm in diameter.
- Flexible and reliable
- Designed for the measurement of alternating currents in a wide range of values: up to 6000A
- Optionally can be supplied for higher currents
- Thanks to its 600mm coil length it can easily be wound in difficult conditions
- Excellent response to rapid changes in current, not being subject to induction of Fourier currents.
- Very high linearity due to the absence of magnetic saturation even in the presence of very high currents, such as in the case of electricity transmission, electric welding or applications involving high power pulses
- The particular closing system allows safe use even when wearing safety gloves
Characteristics
UltraFlex™ is a current sensor with an active part (Rogowski coil) characterized by a robust and reliable structure that allows to measure high currents (up to 6000A) in the most demanding positions, thanks to its 600mm coil length.
Not subject to magnetic saturation phenomena, they offer a very high linearity, a low phase shift and a wide measuring range.
UltraFlex™ can be used on all the analyzers of the latest generation of NanoVIP® family (production from 2015 onwards with automatic recognition of the current clamps) except for the DS model that can only mount the DC clamp.
For the older NanoVIP® analyzers (without clamps recognition), suitable adapters are available to allow their use.
