Hall Effect Sensors most notably offer solid state reliability. 0% of Full Scale (FS) even if its deviations are compensated by offset and gain adjustment during sensor calibration. NIH is one of the world's foremost medical research centers. These kinds of devices are based on Hall-effect theory, which states that if an electric current- carrying conductor is kept in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers that tends to push them to one side of the conductor.
