The basic problem of main pipelines non-destructive examination is reliability and validity of obtained parameters of flaws (including stress-corrosion cracks). One of the most rapid and efficient NDT techniques for main pipelines is the method of magnetic flux leak (MFL) over defect. In accordance with magnetic method canon the examination reliability (that is probability of crack detection st...
The novel contactless current sensors consist of an integrated CMOS Hall effect sensor covered by a thin, ferromagnetic layer structured on its surface. The Integrated Magnetic Concentrator (IMC) layer acts as a magnetic flux concentrator, providing a high magnetic gain which increases the sensor’s signal-to-noise ratio. The sensor is particularly appropriate for DC and AC current measurement. ...
Microelectromechanical systems (MEMS) technology allows the integration of magnetic field sensors with electronic components, which presents important advantages such as small size, light weight, minimum power consumption, low cost, better sensitivity and high resolution. We present a discussion and review of resonant magnetic field sensors based on MEMS technology. In practice, these sensors e...
Adjusting magnetic nanostructures for high-performance magnetic sensors" (2014). David Sellmyer Publications. 259.
— This paper presents a magnetic circuit modeling of closed loop Hall-effect current sensors based on a magnetic equivalent circuit which could be simulated with a circuit type simulator software (PSPICE model). First, the principle of measurement of the closed loop Hall-effect current sensors is presented, Then, the magnetic equivalent circuit (MEC) modeling justified by the engineers' model n...
