A sample size for the Fast Fourier Transform (FFT) (when viewing "Acceleration vs.The vibration sampling rate is inversely proportional to the number of ShapeArray joints viewed.The more segments you select, the slower the data rate.Every segment of a Model 3 SAAF or SAAScan or newer ShapeArray is available for vibration monitoring.Only every eighth joint of a Model 1 or Model 2 SAAF or SAAScan is available for vibration monitoring.There are a variety of things to note when you are collecting vibration data. Time graph and the portion of the ShapeArray from which to collect vibration data Model 1 or Model 2 SAAF and SAAScan ShapeArrays are in 8 segment sections called an Octet Subarray.įigure 4: Selecting Acceleration vs.

Note: For Model 3 SAAF and SAAScan or newer ShapeArrays, there are no subarrays each segment has its own serial number and can be individually selected for viewing vibration data. Select the type of vibration data graph desired and the parts of the ShapeArray the vibration data is for. If a warning dialog appears, click the OK button to close it.įigure 3: The Data and Graphs menu in SAARecorder Click the OK button to close the Basic Settings dialog and click the OK button again to close the warning dialog.įrom the Data and Graphs menu, select the Get vibration data menu item. Ensure that the Use Averaging-in-Array(AIA) mode checkbox is deselected. In SAARecorder, click the SAA Setup menu and select the View Basic Settings option. Step 1 - Disable AIA and Select Vibration Data In order to return to measuring the static shape of the ShapeArray, it is necessary to close all of the vibration graphs that are opened. The static shape of a ShapeArray cannot be measured at the same time that vibration is being measured on one or more ShapeArray segments. The 3 dB bandwidth of the accelerometers used in ShapeArray is set to 50 Hz, so ShapeArray measurements of vibration frequencies above 50 Hz will be attenuated. For example, if vibration data were being collected from 4 ShapeArray (SAA) segments at the same time, the sampling rate would be approximately 200 / 4 = 50 Hz. Vibration mode data is sampled at a collection rate of approximately 200 Hz per segment.

The SAARecorder software interface for vibration presents acceleration data for selected segments as a function of time or frequency.

In SAASuite 3.0 or higher, the SAARecorder application is launched by clicking the Manual Data Collection button.įigure 1: Launch SAARecorder from SAASuite by clicking the Manual Data Collection button For details about collecting vibration data with newer model ShapeArrays, please contact Measurand directly. NOTE: The vibration collection capabilities described in this article refer to Measurand's deprecated SAAF instruments.
