REFERENCE ELECTRODE IMPLEMENTED WITHIN THE FRAMEWORK OF CATHODIC PROTECTION

摘要

The invention relates to a reference electrode (106) for a protection system (100) against corrosion of at least one metallic equipment (102a-c) immersed in water, said protection system (100) comprising a means measuring electrode (112) for measuring a potential difference between the reference electrode (106) and each metallic equipment (102a-c), said reference electrode (106) comprising: - a base (116) having a channel ( 117), a pure silver wire (118) sealed in said channel (117), a first end of which is provided to be electrically connected to the measuring means (112), and a second end disposed outside the channel (117) is covered with a layer of sintered silver chloride (120), and - a cap (122) integral with the base (116), covering the second end and having orifices (123) passing through to allow the passage of water.
