Triaxial accelerometer type 3710 PCB connected to DAQ NI 6225

[FannySol]

Dear Labview community, 

I need help as regards to my assembly for data collection. 

I have for materials : 

- a triaxial DC response accelerometer model 3713B1110G;

- a 3 channel DC sensor signal conditionner model 478B05;

I have already connected the two devices thanks to a wire with 3 inputs. 

Now, I need to link my assembly (accelerometer and conditionner) to my national instruments DAQ device (NI USB6225). 

Do you know what type of wires I need? 

Please find in attachments the model of DAQ and the conditionner I would like to link. 

Best regards

the output of the conditioner is BNC. I assume, but I'm not shure that all BNC shields share one common potential (check: measure the resistance between them with a DMM or RTFM)

Since you have enough differential channels: Use them and configure your input task to be differential.

connect each conditioner output x to AI{x} (inner pin) and AI{x+8} (shield) (x from 0..2 😉 ) 

If all conditioner shields are same common potential, add a 10k to 1M resistor from one of them to AI GND,  or 3 for each otherwise. (you can do that in the connection box there are a lot of AI GND connections 😄 )

An easy way to get connection cables: BNC to BNC cables a usually easy to get. Grab two of them with double length needed and cut them in the middle 😛 

professional next steps involve wire end ferrules and shrink tubing 😉

and think of the strain/pull relief

thanks a lot for your precious help! It is so nice!
