Measurement probe with small magnetometer

摘要

The measurement probe has a measurement device for each of three magnetic field measurement directions. The measurement device (19,21) for at least one direction (33) is inserted in the device (18,20) for one of the other directions (34,35). The measurement devices are conventional ring cores with pick-up coils (18-21).The coils are symmetrically arranged on an imaginary centre line.The measurement devices are arranged in three spatial directions, pref. orthogonally and mutually displaced on a carrier (12). The carrier is mounted in a tubular housing (11) which has longitudinal external guide slots (22)
