Stabfoermige Elektrode mit einer Korrosionsschutzschicht und Verfahren zur Herstellung derselben

The rod electrode (2) consists of a core of an electrically conductive material, and a shell which envelops the core up to one or both of its end regions, and is made of an electrically insulating material. The electrode comprises the shell takes the form of a coating of diamonds applied to the core. Also claimed is a method for producing such an electrode. USE - Used for liquid level detection. ADVANTAGE - Electrode life, also in very aggressive media, is prolonged in comparison with known equipment.
