TF flexible current sensors
The TF flexible current sensors use the Rogowski principle, covering a wide current range without saturation.
Their flexible design and easy opening system enables a quick installation inside electrical panels, making them
particularly well suited for adding measuring points in existing electrical installations, especially when space is limited.
The secure lock technology prevents non voluntary openings of the Rogowski rope.
4.2.5.1. Range
Six models are available, covering a large current range up to 6000 A with openings of different shapes and sizes.
They include a compact and self-supplied integrator, required to shape the current signal.
Due to the specific RJ12 connection, the TF current sensors can only be used with DIRIS Digiware
I, DIRIS B and DIRIS A-40. Used in conjunction with these PMD equipped with RJ12 connectors,
the overall accuracy of the measurement chain is guaranteed.
