ITN Series – Ultra?Stable High?Precision Fluxgate Current Sensors
The ITN Series represents an ultra?stable range of high?precision Fluxgate current sensors, optimized for applications demanding the highest levels of accuracy and immunity to external disturbances. Designed for the precise measurement of DC, AC, and pulsed currents, ITN sensors provide galvanic isolation and deliver consistent performance in high?precision measurement systems.
Operating on closed?loop Fluxgate technology, the ITN Series matches the accuracy, linearity, and resolution of the IT platform while extending mechanical and EMC robustness on selected versions. In particular, the ITN?12?P Ultrastab variant is designed for PCB mounting and features a metal housing to enhance EMC immunity against external interference.
With nominal current typically between 12.5 A and 1000 A, the ITN Series is ideally suited for advanced applications requiring ultra?precise and interference?resistant current measurement.
