IT & ITN

Highly accurate Fluxgate current sensors

IT, ITN - High precision current sensors

The IT and ITN product families are engineered for ultra-high precision current measurement. They are optimized to deliver exceptional accuracy in measuring DC, AC, and pulsed currents while providing galvanic isolation between the primary and secondary conductors, thus contributing to the high performance of the overall system.

IT and ITN Ultrastab current sensors are designed to provide high-precision measurements within a range of 60 to 1000 ADC nominal current, all while maintaining galvanic isolation. These sensors are known for their outstanding linearity, high resolution, and rapid response times. They are intended for panel mounting in various applications where precision is essential.

Within this product family, the ITN 12-P Ultrastab stands out with unique characteristics compared to the other components. It maintains the key features shared by the rest of the family and can also be used for high-precision current measurement. However, ITN 12-P is specially designed for PCB mounting and features a metal housing for enhanced immunity against external interference.

Both IT and ITN current transducers operate based on the closed-loop Fluxgate technology, which ensures ultra-accuracy in any system where they are employed. This technology enables highly precise current measurements, making these sensors suitable for applications demanding the utmost precision and reliability.
