Probe for detecting direct and alternating magnetic fields

摘要

A probe for detecting magnitude and direction of direct and alternating magnetic fields, consisting of a magnetizable core arranged in a chamber inside a probe body and having at least one premagnetization winding and one induction winding which are located on the probe body. The magnetizable core is periodically saturated by an alternating current flowing through the premagnetization winding. The induction winding (sensing winding) supplies a voltage which contains the measurement value of the magnetic field. The probe body is constructed in such a manner that, after application of the windings to the probe body, the probe core can be threaded into the probe body through a threading-in opening. The chamber surrounding the probe core can be filled with a casting material through one or more filling-openings existing in the probe body after the probe core has been threaded in. <IMAGE>
