load cell with labview 6

[Hsin]

Hey guys,

I have to write load cell program with labview 6, but I have no idea how to do it. 

If anyone knows, please give some hints.

Thank you

If you have little LabVIEW programming experience, the link below would be a good place to start:

I've also located a good example on ni.com/community that shows how to monitor a load cell in LabVIEW

I hope this information is helpful.

I did see this example before I post question.

The problem is I don't know the math to transfer the input voltage to load.

And my labiew is version 6, i couldn't find any example regarding to force measurement.

Load cell is ageneric term that could be a piezo crystal or strain gauge.

Which type of load cell do you have?

The "Search Examples" worked fine in LV 6. Search for Hardware I/O >>> Analog input

Hey Ben,

I didn't see the hardware I/O in my search example.

I don't know how to convert the voltage to load again.

From LV

Agian you should figure out the type of load cell.

One gives you a voltage and the other type gives a change in resistance.

I still couldn't fine the hardward I/O

Maybe because the version??

My load cell is SWO-10K for 10000lbs

Resistence is 350 ohms

rated output is 2mV/V

excitation voltage is 10VDC
