The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...
In 2010, the legacy brands of Premier Electronics, Farnell and Farnell-Newark were replaced by Farnell element14 in Europe, and by Newark element14 in the US. The name was taken from silicon, the 14th element in the Periodic Table, which is widely used in electronic components such as integrated circuits and discrete semiconductors. [18]
An important application of the Néel effect is as a current sensor, measuring the magnetic field radiated by a conductor with a current; [3] this is the principle of Néel effect current sensors. [4] The Néel effect allows the accurate measurement of currents with very low-frequency-type sensors in a current transformer without contact.
Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.

Attempts to overcome this fundamental limitation using low frequency coils and superconducting magnetic field sensors have not led to widespread applications. A recent technique, referred to as Lorentz force eddy current testing (LET), [ 13 ] [ 14 ] exploits the advantages of applying DC magnetic fields and relative motion providing deep and ...
