connecting strain gage based pressure transducer to NI USB 9237 and getting the scaling to work properly.

[invzbl_rkl]

I found a vi that is suppose to be compatible with the NI USB 9237. I have connected a couple of load cells to it and applied the manufacturers sensitivity and it works fine. However when I connect a strain gage based pressure transducer http://www.gesensing.com/products/resources/datasheets/NPC_100_04_03b.pdf  to it the vi flatlines before I reach the sensors maximum capacity. The scaling setup doesn't seem to work with this pressure sensor, not to mension I think the info that the manufacturers specs provide are all messed-up. I have tried playing around with the excitatio voltage and the scaling, but can't figure it out. I really don't know where to go from here, at first I thought it was an equipment problem, but now I just think it has something to do with how the vi is written and how its scaling. If I can't figure out how to fix this within the next couple of days I have to return 9237 and use something else witch I really don't want to do. Can anyone help?

I have attached the the vi and a picture of what is happening when I run it.

Hello invzbl_rkl,

If I am reading the datasheet correctly the sensitivity of this device is 5 μV/V/mmHg, not 2 mV/V/mmHg.  If you could change your code by dividing my 1,000,000 rather than 1,000 the scaling would be improved.

Let me know how this works.
