Question

Firstly hello to all. I’m looking to create a vi that will
take a single logged output from a thermocouple and monitor the temperature and
produce a Boolean when the temperature has stabilised for a pre determined time
say 1minuet. I have managed to find a couple of examples on the forum but one
will only run on V8.2 and I have V8, the other is for more than one channel
witch is fine I can always reduce this, but it was the timing feature I was
having difficulty with. I looking to monitor the temperature of a motor until
it has stabilised prior to testing and then to use this temperature as a
reference. Pleas forgive my ignorance if this is a very simple thing but I’ am
learning and really enjoying it. Thank you in advance for your answers.

Answer 1

Hi
Graham, thank you for you reply.
What I’ am trying to achieve is a vi I can use in a motor
testing setup, a part of this would be to warm the motor up until the exhaust
air temperature has stabilised, this takes approximately 10 minuets. I was
thinking of just letting the motor run for this time and leave it at this, but
some motors warm up quicker that others and. I am basically looking for a vi with
an adjustable temperature window of say ±5 C° in 1° increments, timing wise 1minuet
to 10min the adjustment is so I a can use this for another application. I tried
to adjust the code I found at the link below but had a little difficulty with
the timing. Thank you so much for your help it’s much appreciated.
