Temperature measurement

Bump!

Since that last post, I picked up the Cole Parmer thermometer. I'm preparing to run a series of test on the chiller, to measure the performance.

Thanks to Capt Foo Foo, I now have the software that goes with the chiller. It has full logging capability.

Now to figure out the validity of the chiller's temp readings... then a mod for more flow!

For now, since money is tight, I'm concentrating on picking up a multimeter and an oscilloscope. Both of those will also allow me to complete the redundant power array, another project that's been sleeping...

did you read the specs on that thing ?
"Immersion depth - Total", and its 275mm long
wheeee

Yep, sure did. I even have a compensation formulae, from Cole-Parmer, for partial immerson. Surprisingly irrelevant (but will still be applied).

sounds good Ben
your eyes are doubtless better than mine, but you will find the constant reading of that thing a pain
perhaps you could set an optical sensor to 'read' the reflective bead . . . . .
(thinking GPIB here 'cause you don't need the bandwidth)

Why don't I just remove my reticular implant, and hook it up to my pc, and log the data?

I see your point. I'll try it out and see how it responds. Either way, I need to do something, anything... if I have to re-run the whole test series once i have my temp probes hooked up to my PC (the ones that will be used for the testbench), then I'll do that.

Either way, I have to get some decent results, so that when I swap the pump, I can measure the difference in performance of this chiller. No decent results -=> the pump swap is on hold until I can get some serious data.

In the mean time...


Here's a link to a table generator (for temp probes) I thought might come in handy:
