HallinPower®: Flexible current sensors from a few amperes to several mega amperes

Our expertise in current measurement includes both new and proven techniques: First and foremost is model-based current measurement, an innovative method that uses mathematical models and advanced algorithms to accurately measure current. This method is constantly evolving. In addition, we rely on established and robust methods such as the differential field principle, which uses the difference in magnetic fields for precise measurements, and the ring integral principle, which enables us to accurately measure currents by integrating the magnetic field along a path. This is how HallinPower^® technology was created.
