Problem with NI-9203

[azizan90]

HI, im new to labView Programming and CompactRio. Currrently i used CompactRio to implement my Final Year Project. I need Some advice regarding the connection between Pt100(4-20ma) and NI 9203 Module because i didnt get the correct signal at my labview front panel. What should i do?

Well, let's have a look at your sensor: You wrote Pt100 (4-20mA) , so  you have a Pt100 temperature sensor and while this is a resistive sensor you would need a signal conditioner, that will convert the Ohms into mA that your 9203 can read .  What type (link to datasheet? )

You would also need a powersupply that fit the needs of your conditioner (usually a 24V supply ).

Useful bonus information to the forum:

Temperature range?

Other sensors connected?
 How are they connected to ground?
