Looking for a suitable displacement sensor (LVDT) for NI9218.

[FrederikB]

I'm working on a testrig using the Compact daq system.

The system needs to be able to power and read-in a loadcell and a displacement sensor.

To keep the test rig as compact as possible (Portable system), I want to use the NI9218 module in my compacDAQ system, which can power and read-in 2 channels/sensors.

Can somebody help me with the following?

Which type of displacement sensor (LVDT) is suitable to be powered/read-in via the NI9218 module? (If possible, without an extra power supply) 

Which specs for the LVDT sensor a important to be able to work with the NI9218 module?

Best regards,

Frederik

Hi Frederik,

So

Consider the NI 9218. It can provide exictation of 12V at ~50mA per channel and read the 5 or 10V output from the DC LVDT. To use this 12V excitation a 9-30V power supply must be connected to the Vsup pins.
