Tech/Engineering - Patents / predicting the health of a hydraulic machine, non-pumping frequencies
English term or phrase: trend
The controller is configured to: trend the amplitudes of the dynamic pressure signals at non-pumping frequencies over time; compare the trended values to a threshold level; and conclude the hydraulic machine is damaged or worn when the trended dynamic pressure amplitudes exceed a prescribed threshold level.

To use this type of analysis for monitoring pump health, the dynamic pressure
amplitudes of undesirable non-pumping frequencies can be trended over time during periods where the pump is operating at the same steady-state condition. One way to do this is to simply sum ail dynamic pressure energy that exists at non-pumping frequencies, and trend this value. Borrowing the term "signal-to-noise ratio" from signal Processing, where the pumping frequencies can be thought of as the signal, and ail other frequencies can be thought of as noise, this summation of dynamic pressure amplitudes at non-pumping frequencies can be referred to as "noise power".

Explanation:
trend the amplitudes of ... => it is not about simply recording the variations of (whatever) but includes a further step - processing the raw data in order to establish / calculate the trend these variations are showing.

As explained in the ST itself:

"One way to do this is to simply sum ail dynamic pressure energy that exists at non-pumping frequencies, and trend this value"

That would a summary description of the "processing" of raw data in order to establish the "trend".

Explanation:
Le mot trend comprend une notion de tendance et donc de variation de valeurs

disagree  Daryo: roughly speaking yes, but more precisely a big NO. A "trend" is more than simply recording a series of readings along the axis of time.
