Pump failure detection unit uses Fourier analysis of pressure sensor measurement to determine if characteristic frequency exceeds reference amplitude |
| 摘要 |
<p>A pump (1) failure detection unit (4) has a pressure sensor (2) with frequency analyzer (5) and processor using a discrete Fourier transform to compare (6) the amplitude of a characteristic frequency with a reference amplitude to determine if it exceeds a threshold. Independent claims are included for the procedures used by the failure detection unit.</p> |
