Conductivity sensor for use in steam turbines
First Claim
Patent Images
1. A conductivity sensor for in situ measuring of impurities in steam used to drive steam turbines comprising:
- (A) a base mountable on a portion of said turbine directly in the steam path;
(B) said base being comprised of a relatively flexible metal foil so as to conform to a curvilinear surface of a turbine part in the steam path;
(C) an electrically insulating layer disposed over a surface of said metal foil base and having a thickness so as to be relatively flexible after application to said base;
(D) a metallic electrode array on said insulating layer and having a thickness so as to allow flexing with said insulating layer and base;
(F) said electrode array being exposed to and being non-corrodible in said steam;
(G) said electrode array being of sufficient thickness and electrodes of said array being spaced from one another at a distance to allow deposition of steam impurities between said electrodes to establish an electrically conducting path therebetween.

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.
