Wear Ind ica tor for Sacri f ic ia l A n o d e WO 2004101851 (Performance Metals Inc.) Wigg, M.; Leipert, H., et al. Apparatus for indicating when a predetermined portion of a sacrifi- cial anode has been corroded com-

prises a detector embedded within the interior of the sacrificial anode initially at a predetermined dis- tance from an exposed exterior sur- face of the anode. The detector detects the absence of sacrificial anode material when the predeter- mined portion has corroded and generates a detection signal. A monitoring system communicates with the detector and generates an indicator signal when a detection signal is received.
