Highly accurate Fluxgate current sensors

IT Series – High‑Precision Fluxgate Current Sensors

The IT Series current sensors are engineered for ultra‑high‑precision measurement of DC, AC, and pulsed currents, providing reinforced galvanic isolation between the primary and secondary circuits. Designed to deliver exceptional accuracy, these sensors are widely used in applications where measurement stability and resolution are critical to overall system performance.

Based on closed‑loop Fluxgate technology, the IT Series achieves outstanding linearity, high resolution, and fast response times, enabling precise current monitoring across a nominal current range typically from 60 A to 1000 A.

Intended primarily for panel mounting, IT current transducers are well suited for precision industrial and laboratory environments requiring reliable, long‑term measurement accuracy.
