Title:
荷電粒子の流れを測定するためのセンサおよび方法
Document Type and Number:
Japanese Patent JP2005529338
Kind Code:
A
Abstract:
A current sensor ( 1 ) is disclosed for measuring a magnetic field ( 8 ) induced by a current of charged particles ( 3 ) having at least one magneto resistive sensor element ( 2;6;12;16 ) for enclosing the magnetic field induced by the current of charged particles, the magneto resistive sensor element being arranged perpendicularly to the current ( 3 ) during use. A method for accurately determining a current of charged particles is also disclosed making use of the current sensor ( 1 ). Further a protective switch device ( 30 ) is disclosed for protecting a user of an electrical device ( 31 ) by switching a supply current to the electric device off in case of malfunction of the electric device is also provided comprising the above current sensor ( 1 ).
