Hi Voon,
I haven't had much experience with pressure sensor, but I am guessing there is some kind of conversion from pressure unit (bar? psi?) into voltage?
You can convert the voltage data into pressure data by several methods, few that I can think of:
1. DAQmx Scale
--> Go to MAX>>My System>>Scale>>Create New
--> Then fill in which conversion type suite you based on the sensor manual, save the scale
--> In LabVIEW, if you use DAQ Assistant, use Custom Scaling and use the saved scale previously
2. LabVIEW
--> If you acquire the data in LabVIEW then you can create a 'conversion' formula in LabVIEW
Hope it helps.
Sincerely,
Krisna

Hi krisna,
Ya, I follow the step you given to create the new scale in MAX. I m using the calibration datasheet for sensor calibration to plot and get the XY-equation. I am not sure whether I m doing it correctly.
Anyway, thanks ya.
Best Regards,
Voon Loong
