Paired with the zero-flux method, a proprietary thin-film Hall element makes possible high-performance current sensors.

Wideband current sensors use the "zero flux method (Hall element detection type)" to measure. High-frequency currents are detected with the winding (CT method), and low frequency currents including DC are detected with the "Hall element." ● Hall element detection Hall element detection is characterized by a simple structure and a sensor section that can easily be downsized. Hioki combines our own proprietary thin-film Hall elements with the zero flux method to deliver sensors that can conduct measurements over a wide range of frequencies, from DC to MHz bands Ideal for waveform observations using a MEMORY HiCORDER or oscilloscope, Hall element detection achieves a high S/N ratio in the wideband range, making them particularly well-suited for design verification of electronic circuitry such as high-speed signal circuits. ● Zero flux method The zero flux method is a measurement method used in both high-accuracy and wideband sensors. As the principles the sensor is based on give it both low operating magnetic flux level and low insertion impedance, it is characterized by its lack of influence on the measured object and low instrument loss.
