Title:
酸素センサにおける漏れ電流の検査方法
Document Type and Number:
Japanese Patent JP4188447
Kind Code:
B2
Abstract:
A method for testing for leakage currents in an oxygen probe, in particular a planar lambda probe, having at least one heating element, one external electrode and one internal electrode, and a solid electrolyte arranged between the electrodes, a first voltage being applied to the heating element. A second voltage is applied to at least one of the electrodes, the second voltage being selected so that the potential difference between the electrode and at least one area of the heating element is positive.
