Sticking temp-probe to FVs

I am really struggling to get any tape to stick to my FV/plastic keg. I want to get a length of tape and some tissue to secure and insulate a 2" probe to the side of the vessel for my Inkbird controller, but even duct tape is just falling off... I am not sure if it's the plastic or because the temperatures lead to a lot of condensation.

How can I do this in a way that it will a)stick b)can be removed without leaving loads of sticky gunk later?

Thanks!

Is it dry? - I just use sellotape, but have also used masking tape.

Maybe that's all it is. But if you are cooling your beer it gets condensation, maybe once the tape is stuck this is less of an issue.

If others use regular stuff I'll be more careful drying first next time.

Make sure it's dry and use multiple pieces. Alternatively I have seen done people use bungee cords or ratched equivalents to secure a probe under bubblewrap.

Use some wide elastic as used in clothing, about 1" (2.5cm) wide, sew velcro on both ends and put this completely around the fermenter.
Make elastic shorter than circumference of fermenter so that you need to stretch the elastic for the velcro ends to stick together.
Tuck some bubble wrap, folded, under your elastic and fit probe between the bubble wrap and the fermenter.
Works a treat!

Fit a stainless steel thermowell (available from The Maltmiller) and your problem will be over. Whats more your temperature control will be more accurate because the probe will be be where it should be. In the middle of the fermenting beer. Just take care where making the hole in the FV. It needs to be a tight fit.

Edit
If you are controlling the temperature of barreled beer fill a bottle with water stand it next to the barrel and stick your sensor in the bottle. That way you will have less fluctuations in temperature.

I make a bubblewrap pouch and then use duck/gaffer tape to fix it to the FV. Good tip - once you've made the first tape across the tissue/bubblewrap, fit two more strips at right angles just where the edge of the tissue/bubblewrap is. Like an H pattern. Then it'll stay.

if your sticking the probe to the exterior of the vessle try silicone sealant i have used it in industrial situations to place cabeling on stainless catering machenery
and should pull off fairly cleanly when you want to take it off again

I just use sellotape to fix the probe to the outside of the plastic fv. Never fallen off yet.

I found micropore best at resisting condensation, that said duct tape should have worked but I never tried it.

Duck tape works fine for me, just make sure the surface is dry before sticking it on.
