VI for loadcell

[Teljo]

Anyone here knows how to set up the VI for loadcell sensor using labview 7.1 with a SCC-SG24.Connection of the loadcell to the SCC-SG module is working,i just need to know how to draw the VI.I have attach the model of the loadcell and SCC-SG24 to the mail.

Hi Teljo,

There is actually a great way to get this code generated for you in LabVIEW.  I am assuming you are using a windows system, but if this is not the case let me know.  The best way to get started is to place a NI DAQmx task constant on the block diagram of your VI.  Then you can right click on that and select

New NI-DAQmx Task»MAX

You can then set all the settings for you data acquisition in the MAX window.  The next step would be to say done in the MAX menu.  Now you can right click on the Task you have made and go to

generate code»Configuration and example

That should generate code that will give you the ability to record strain gauge data.  Please let me know if you need any further help, and if you do please add your system specs such as operating system, and DAQmx versions.  I would recommend downloading the most recent version of our DAQmx drivers, since you are running LabVIEW 7.1.  You can get those files at http://digital.ni.com/softlib.nsf/MainPage?ReadForm&node=132010_US.

Have a great weekend,

hi  Michael,

       Thank you for your help,Still i have some  problems,.which unit is suitable for the loadcell masurments.Because i getting  some different type of values.I just attach the things that i get today.Please give a look and send your  suggestions .

thanks

Hi Teljo,

I can not really tell a lot from your screen shot, because everything dealing with how you are taking the acquisition is in the DAQ Assistant.  If you like you could generate the code from that DAQ Assistant like I described above, then I could understand you application a little more.  I would guess that your load cell is taking measurements in strain, so you need to set up the task in the DAQ Assistant to read strain.  The link below does a great job of explaining DAQmx and how the VIs work, including the DAQ Assistant.

I was looking at your spreadsheet data, and the recorded voltages appear very small, which is expected for a load cell application.  I was wondering what was the data input into the first channel, which is the first colum in the excel spreadsheet.
