20090314064 | PRE-SIGNALING MAGNETIC PLUG - The invention relates to a signaling magnetic plug for a liquid circuit, the plug including a first magnetic electrode and a second magnetic electrode for coming into contact with the liquid flowing in the liquid circuit when the magnetic plug is mounted so as to detect the presence of metal particles that might be contained in the liquid. According to the invention, the plug also includes a preferably non-magnetic intermediate electrode disposed between the first and second magnetic electrodes while also being designed to be in contact with the liquid flowing in the liquid circuit when the magnetic plug is mounted, whereby said plug enables the presence of such metal particles to be detected early. | 12-24-2009 |
