Owning Palette: Vibration Level VIs

Requires: Sound and Vibration Toolkit

Computes the maximum and minimum levels of all previous values and the difference between the maximum and minimum levels of scaled signal [EU] or even-angle signal [EU] . scaled signal [EU] should have a zero DC component. You can attenuate the DC component with hardware AC-coupling filters and with software high-pass filters. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.

SVL Max-Min Level (Time Waveform) (1 Ch)

scaled signal [EU] specifies the scaled signal expressed in the selected engineering units. To obtain a properly scaled signal, you can use the SVL Scale Voltage to EU VI or define a virtual channel in National Instruments Measurement & Automation Explorer (MAX).
t0 specifies the start time of the waveform.
dt specifies the time interval in seconds between data points in the waveform.
Y specifies the data values of the waveform.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
restart averaging specifies if the selected averaging process has to be restarted. The default is FALSE. When you call this VI for the first time, the averaging process restarts automatically.
max level [EU] returns the maximum level in engineering units [EU].
min level [EU] returns the minimum level in engineering units [EU].
max-min level returns the difference between the maximum and the minimum level in engineering units (EU).
unit label returns the selected engineering units.
error out contains error information. This output provides standard error out functionality.

SVL Max-Min Level (Even Angle) (1 Ch)

even-angle signal [EU] specifies the signal, in engineering units, resampled at an even-angle interval.
r0 specifies the start of the revolution index.
dr specifies the revolution interval between two sequential samples.
even-angle signal specifies data resampled at even-angle intervals. The samples are synchronous to the rotational speed.
even-angle channel info specifies information about the measurement configuration used to acquire the resampled data.
Note You must wire even-angle channel info when performing extended measurements. Do not modify the even-angle channel info values. If you want to view the information, you can create a custom probe.
