How to connect 2 wire pressure sensor to NI9208

Dear all

I need help on connecting the 2 wire pressure sensor from GE unik5000 to NI9208.

The data sheet is not clear regarding the electrical connection. I attached the data sheet.

Thank you in antecipation

It's a two wire loop powered milliamp sensor. Connect the positive red wire to the positive of the 24V supply and the negative wire to your NI 9208 analog input. Then connect the COM of the module to the negative of the 24V supply.

Dear MarkCG

 
I have connected the pressure sensor to NI9208 as your recommendation. 
 
Power Supply: +24volts to Vsup (NI9208)
                         COM   to COM (NI9208)
Sensor:         +ve (Red) to Vsup (NI9208)
                      -ve (White) to AI0 (NI9208)
 
The signal displayed is 21.9999mA and remain invariable for different water level.
 
There are something I did wrongly?
 
Regards

Did you connect the negative of the power supply to one of the COM pins of the NI 9208?
