Need help with temperature sensing program with timed loop

[rvdnfg]

I am a new user of LabView 8.0.  I am trying to write a program that will sense a temperature using a thermocouple.  I will then have a loop to constantly check to see if a certain temperature has been reached, if not it will turn on an indicator light.  I've tried writing it using a while loop to check for the temperature condition as well as a case structure.  Any help would be appreciated.  Thanks.

Hi,

Which hardware are you using??

Nevertheless, you will find an example VI with examples shipped with labVIEW called "temperature system demo.vi" a simulated temperature measurement program.

replace the temp simulation with hardware thermocouple acquisition VI's

That VI it might suit your purpose

find attached that VI

Any doubts, do get back

regards

Dev

Thanks for the help.  I'm using a Vernier Temperature Probe.  The digital thermometer VI randomly generates a temperature and I need to acquire an actual one through the analog input on ELVIS.  I used a VI from Vernier to test the probe once I wired it to the board.  So, I can acquire a temperature reading, I'm just not sure how to integrate that into my VI.  Any help would be greatly appreciated.  Thanks.

Hi,

First of all look for the Temp SubVI in th blockpanel of the temp demo vi. This Vi have to be replaced by a subvi that reads your temperature thru elvis.Then open the VI you used to succesfully read the temperature. The indicator wich shows the temperature should be the output of the subvi . Create a SUBVI of this VI and use this subvi to replace the Temp SubVI in the temp demo VI...
