Section: claims

1. A method of making an electrochemical corrosion potential sensor electrode comprising the steps of: providing a sensor tip;  connecting a conductor to the sensor tip;  providing an insulating member around the conductor;  providing a connecting member around the conductor;  providing a sleeve which fits over the insulating member, a portion of the connecting member, and a portion of the sensor tip;  forming inner threads on the sleeve;  forming outer threads on at least one of the sensor tip and the connecting member; and  engaging the inner threads with the outer threads. 2. The method of claim 1, further comprising the step of forming the insulating member of sapphire. 3. The method of claim 2, further comprising the step of forming the connecting member of alloy 42. 4. The method of claim 3, further comprising the step of brazing the insulating member to at least one of the sensor tip and the connecting member.
