FIELD: medical engineering.
SUBSTANCE: device has handle and non-magnetic metal protective casing having two sensitive elements mounted on non-magnetic panel in one plane, in perpendicular to its longitudinal axis, in parallel to each other. The elements are manufactured from permalloy cores and coils which windings are connected to each other in gradientometric way and function as excitation and measuring windings. Magnetizing coil is mounted between the sensitive elements in perpendicular to the first pair the sensitive elements, The second pair sensitive elements is additionally introduced into design. The elements are manufactured from permalloy cores and coils which windings are connected to each other in gradientometric way and function as excitation and measuring windings. Besides, the magnetizing coil is manufactured on ferrite rings.
EFFECT: high accuracy and reliability of measurement data.
