Abstract

A conductivity sensor for placement on a curved steam turbine component within the steam path. The sensor includes a metal foil base over which is deposited an electrically insulating layer such as glass. The base and insulating layers are of such thickness so as to be flexible so as to conform to the curved surface. An electrode array is deposited upon the insulating layer and spaced so as to accommodate for deposition of steam impurities onto the insulating layer. Flexible links connect the electrodes to electrical leads so that conductivity indications may be obtained.
