Hello,
I am performing testing on load cells over a thermal range (40-135F).
Currently I have a NON-insulated area made of Bent Sheet metal, this
area is relatively closed up with an opening on one side for the
application of hot/cold via a ****table ceramic heater / air
conditioner respectively.
Currently I have no problems with heat, I can hold it relatively
stable to +/- 0.2 degrees over (80-130F).
On the cold side I would like to get down to 40 deg F, . the problem
is stability. The unit gets down to 45 deg f, then begins to frost
up, then the output slowly increases to about 55 deg F where it
stabilizes off.
I understand one method would be to get a frostless, however I think
that it may introduce thermal output fluctuations.
Any Suggestions... I would like to hold +/- 0.2 deg F from 45 deg F-
Room Temp
Thank you for your time
