USB-6211 Pressure Transducer Noise Error

[Spaulding9717]

Hello all,

I have been trying to connect a pressure transducer through my DAQ by reading the voltage and when using a multimeter to checking the voltage reading from the wires I'm getting exactly what I want, but when I look at the reading through labview I'm getting so much noise that I can't even acquire a solid enough reading for testing. When playing around with filters and measuring blocks I am pretty sure that some way of reducing the noise and getting the reading of the peak amplitude would do it, just not sure where to go next as I've tried so many options like that already.

Issue was resolved. Merely a grounding issue that I looked over.

Can you please let us know how you fix it?

It was a grounding error. One of those simple things I merely looked over and felt really dumb about after. All it was, was making sure I grounded the wires on the DAQ device itself. That easy. Funny how it's always the little simple things that create the biggest errors and headaches sometimes.

Hello

thanks for reply.

i have exactly same issue which is bothering me a lot 😞

i have two wires connected to AI0 & AI8. Do you mean I should ground those wires with the AI GND pin ?

It's been a few years since I have looked at this, but if my memory is correct, then yes that will do the trick.
