Abstract
The invention is aimed at improving valve pinpointing and reading devices by proposing to activate a magnetic detection source allowing measurements regularly-distributed in a circle around an axis at predetermined measurement positions. An exemplary locator comprises a casing () provided with a mechanism for detecting and analyzing the magnetic field of the magnetic dipole of the valve. It comprises:—a magnetic detection source () able to detect and measure the magnetic field of the magnetic center of the valve at predetermined measurement positions distributed in a circle around an axis (X-X'), linked to—a microprocessor () for analyzing the measurements and for generating detection signals.
