LVDT position sensor and NI cDAQ

[Yltsä]

Hi

Is there any good way to use LVDT sensor and NI cDAQ system? The sensor is used for a high precision position measurement, the total displacement is just about 10 micro meter.

What NI cDAQ module would be good and do we need an external signal condition module? Can you recommend some? The sensors we can find..

BR,
Ilkka

Only PXI based cards are available for LVDT in NI's portfolio. https://www.ni.com/en-us/shop/category/position-displacement.html

Usually the LVDT manufacturer also offers signal conditioner/amplifiers. Here are some that I found on Google,

Hi Santhosh,

Thank you very much for the links. I also conducted a search before, but I didn't notice all the links you provided.

The PXI-based solution would be a little too expensive and complicated to maintain. We will use the NI cDAQ-9189 chassis, so the only option is to use third-party signal conditioning.

Best regards, Ilkka
