ABSTRACT:
A tube sheet with an attached reference electrode is provided for use in heat exchangers and condensers. The reference electrode includes a bolt, one or more elastomer cylinders placed over the bolt and flanked by strees distribution washers on both ends, and a non-metallic housing containing the reference electrode element and having an internal thread at one end matching the thread on the compression bolt. This assembly is inserted into a tube on the tube sheet, only the housing containing the reference electrode element is exposed. The housing may be rotated to cause the elastomer cylinders to expand and lock against the inside wall of the tube.
