NI 9219 with Omega Pressure Transducer (PX409-1.5KGI)

[chadg1994]

I need help wiring my Omega PX409-1.5KGI (4-20mA output) Pressure Transducer to my NI 9219. Attached are pictures of my transducer and Omega Regulated Power Supply, 24 Vdc, 400mA (PSR-24L).

Hello,

The NI 9219 does not support external excitation, and only provides an internal excitation of roughly 2.5 V. The below article explains this a little bit further.

Also, 24 Volts seems like an awful lot for a power source for a pressure sensor. Is there some kind of documentation that shows how much voltage your pressure sensor requires?
