The sensor has two flux concentrators (3,4) and a sensor to measure a magnetic field. The flux concentrators (3,4) are separated by an air gap (5). Two Hall elements (1,2) serve as the sensor. The Hall elements (1,2) are arranged outside the air gap (5). At least some of ...
Little Bee B1 - A high performance current & magnetic field probe Operating Instructions are located in the getting-started folder The Little Bee B1 is an open source magnetic field and current probe based on an Anisotropic Magneto-Resistive (AMR) magnetic sensor. It directly senses magnetic fiel...
The directed field array comprises a cylindrical solenoid <B>10 </B>and a base <B>20 </B>located transverse the solenoid axis <B>11. </B>An array of mutually spaced apart posts <B>24 </B>extends from the base <B>20 </B>such that the magnetic field <B>22 </B>passes through...
These probes convert the voltage induced in an air core coil by the AC magnetic field that surrounds the current being measured. They have low impedance and lack the heat generation, saturation, and hysteresis caused by magnetic loss. AC zero-flux type current sensors These devices improve the ...
in [3]. In general, the relevant quality of such sensor probe is the minimum detectable current and the magnetic sensitivity. Both of these values are frequency dependent, and the former also depends on the spacing between current path and sensor tip. To maintain superconductivity, SQUIDs need...
(TPD)of eddy current by directly measuring the distribution of interior magnetic field inside solid conductor.The research results indicate that TPD is relevant to the shape of coils and stimulating magnetic field in addition to the electrical conductivity and magnetic permeability of conductor as well...
Magnetic field (11) sensor has a first Hall probe (13), with a first entrance and a first exit, which is so designed that the first Hall current flows in the first Hall current direction when a first input signal is applied to the first entrance. The first Hall probe supplies a first...
