Hall sensor

Алгоритм синтезу SPICE схем заміщення гальваномагнітних перетворювачів Холла

The work presents an algorithm of synthesis of SPICE equivalent circuits for galvanomagnetic sensors based on Hall devices. By means of typical library elements circuits were composed in order to take into account magnetic values and sensor’s orthogonal coordinates that are not supported by SPICE. The obtained modeling results fit the results of experimental investigations and form the basis of the sensor’s calibration procedure.

The Magnetic Flux Leakage Method of Railway Track Diagnostics and Ways of It Modernization

Ways of modernization of the information-diagnostics system with which the Lviv magnetic inspection carriage No442 is equipped are considered in the article. The Magnetic Flux Leakage Method (MFLM), that has some advantages over widely used now ultrasonic method, is applied there for rail diagnostics. The Magnetic Flux Leakage Method is used in Great Britain, Iran, USA and the countries of the former USSR.
