LVDT acquisition with CRIO

[vincentlg]

Hello,

I have a CRIO 9024 and i want to use it with 4 LVDT sensor. I found a card for CRIO (RDK 9316 from SET, recommanded by NI) but it seems it only works with 1 LVDT.

Does it exist a CRIO card which admit multiple LVDT acquisition/excitation ? it seems difficult to find...

Thanks a lot 🙂

Some possebilities:

Use LVDT conditioner with DC output or LVDT sensors that already have a DCV output

or

Get a decent sine generator and 5 simultanious analog inputs

read the exitation and the 4 LVDT signals , apply a tone detection  🙂
