Acquiring Temperatures

Сообщение ginos »

hallo!
I am newbie in labview and i am planning to make a vi which will gather temperatures using several thermometers such as thermocouples, thermistors and RTD's with platinum resistance.
I use a SCXI 1000 chassis with scxi 1102b module. I want to use 4 channels each one acquiring a different temperature.
My first problem is how can i calibrate the detectors and how to build the block diagram.. :help:
THANK YOU IN ADVANCE!

Hello ginos,

look on the Examples, how to asquire analog data using NI DAQmx VIs in LabVIEW Example finder. I think you don't need high frequency asquiring temperatures, so you can use one sample read DAQ, you don't need buffered data for your issue.

If you want to calibrate your sensors, you need a scale factor and offset if they have linear characteristic kurve, or you need polynom coefficients even if they are non-linear.

As first try to asquire signals, after them we will look how to calibrate your signals.

Regards, eg
