How do I use AI Temperature with multiple thermocouple types?

[villalro]

Hi,

I am trying to read temperatures from thermocouples. I have the PXI-1112 module. I have 3 thermocouple types. Is there a way to use the AI temperature VI to process all thermocouples with a single wire connection? The VI has an input for thermocouple type, but does not accept arrays. How can I assign a different thermocouple type to each channel?

Thanks

Hello Villalro,

Are you using the DAQmx Create Virtual Channel.vi in your application?  Below is a great example of how to measure three different types of thermocouples all in the same task.  If you are still not able to create the task correctly, you might try building it in a DAQ Assistant.  Once you are able to create the task correctly in the DAQ Assistant, you can convert it into DAQmx code.  Right-click on the DAQ Assistant and then select Generate NI-DAQmx Code.

Villarlo,

Did u mean SCXI 1112 modules??

My bad, it is an SCXI-1112, and it does support DAQmx.
