I made a CFC a month or so ago which worked great on the first use. However, I got tired getting down on my hands and knees to check the inlet temperature indicator on my pump (pump to the fermenter). So....I bought this inexpensive indoor/outdoor digital temperature indicator at WalMart for less than $10. I encapsulated the RTD(?) in JB Weld and epoxied it into a 3/8" brass plug in a "T" at the CFC outlet. I tried it out on hot water and it seems to perform slick. I will try it out Sunday during a real brew session.
Perhaps the accuracy is questionable, but using it with the CFC, I'm only looking for "tends" to set the optimum wart flow.

Tie wrapped to a piece of specially fabricated aluminum...
How can you question the accuracy when the device is named "Acurite"?
Looks great, Ric!

It looks very cool, Ric. I hope it's reliable enough to continue to work over time.

Is JB Weld foodsafe?? Looks quite nice. I wonder how quickly it reflects a change in temperature...

The quantity of JB Weld is small and I persomally am not concerned about the food safety aspect. I'm going to try it out on hot wart this weekend and will then check to see if there is any deterioration. The coating over the RTD is pretty thin but it's also probably a good insulater. From the food safety aspect perhaps a better choice would have been a clear epoxy resin (Rev. 1). Maybe others will chime in here.
The temperature "probe" protrudes into the "T" about 1/2". It seemed to respond well during the hot water trial run.

I have a much easier way to accomplish what you are doing, without adding JB weld or epoxy to your brew.

JB Weld says it OK for drinking water pipe repair.
