<p>A system comprises a rotary machine (70), a (21) sensor and a processor (23). The rotary machine (70) has a component (14, 15) that operates on a fluid. The sensor (21) senses pressure in the fluid. The processor (23) generates a diagnostic indicative of wear on the component (14, 15), based on process noise on the pressure.</p> |
