Patent Images
1. A system comprising:
- a rotary apparatus having a component for operating on a working fluid, the component comprising a turbine, a compressor, a fan, a turbofan or a blower;
a sensor that senses a working fluid pressure of the rotary apparatus and monitors process noise on the working fluid pressure; and
a processor that monitors process noise on the working fluid pressure and generates a wear diagnostic indicative of wear on the component as a function of the process pressure noise;
wherein the wear diagnostic is correlated with a physical change in the component of the rotary apparatus; and
wherein the physical change is due to damaging interaction with the working fluid.

21. A diagnostic pressure transmitter comprising:
-
a sensor that senses a working fluid pressure of a rotary apparatus having a rotary component operating on the working fluid, the rotary component comprising a blade or vane of a turbine, a compressor, a fan, a turbofan or a blower; a processor that monitors process noise on the working fluid pressure, generates a wear diagnostic as a function of the process noise, and generates a wear indicator as a function of a change in the wear diagnostic; and an interface for transmitting the wear diagnostic and the wear indicator to a monitoring system; wherein the wear diagnostic is correlated with a physical change in the rotary component of the rotary apparatus; wherein the physical change is due to damaging interaction with the working fluid; and wherein the wear indicator is indicative of abrasion, erosion, pitting, corrosion, deformation or liberation of an airfoil section of the blade or vane. - View Dependent Claims (23)
