Hello All,
I’m new here on the forum but I’m using Labview for a several years now (mainly as a user, not as much as a programmer).
Now I’m working on a multichannel vibration project and ran into some problems.
The thing I want is a 3 or 5 channel (option differs per measurement) vibration velocity measurement with a FFT spectrum (per channel) from 5 upto 1000 Hz and a RMS value measured from 10 upto 1000 Hz. (so velocity in mm/s vs frequency in Hz).
Both values need to be shown in a chart and as a value and on request (via a knob) to be stored in a txt file.
I tried several existing vi’s but never got one working right.
I’m using a cDAQ 9188 with 2 NI-9234.
Accelerometer (IMI) with a sensitivity of 100 mV/g.
Problem is, sometimes I get the spectrum working another time the only the RMS value.
Sometimes the storing of the values is the problem.
Can anyone assist me in this?
Labview version is 2011 FD.
SVMS 2010.
The example is one of our sister organisations.
Regards,
Mourik
