Where best to place the PID thermostat?

[user 47834]

I used to have a half pound bag of it from the days where I was 'experimenting' with how you could light a campfire with thermite. Long since got 'disposed' of (safely)

Agentgonzo was in the 'ra

Does that stuff not dry up and stick? Could make removing the probe a bit tricky if so.

To be fair @rory I don't know, because I've always used the white silicone grease (about 25yrs old from the darker recesses of my toolbox): 32717 | CRC Silicone Grease 10 g SILICONE GREASE Syringe | RS

Also I tend to use digital temp sensors (DS18B20) which are dirt cheap so I just stick them in and leave them

If the PID thermostat is placed inside a thermowell I seem to recall that you need some sort of thermal grease to make it work efficiently, is that correct?

Mine seem to work fine in a wortometer and in a normal thermowell.

What ever rocks your boat!

In my last modification for a RIMs tube probe I ditched the thermowell altogether and screwed the probe directly into the fitting so the probe is submerged directly in the liquid. For my kettle probe it is shared with my HLT so I need to swap the probe over when I'm diverting power from the kettle element to the HLT element so need to be able to move it around. Not really had any issues with the probe not reacting quickly enough. Its a decent fit and since its horizontal it will drop a bit so the probe tip will be in contact with the side or end of the thermowell so cant see you're going to bet better than metal on metal contact even if it is a small point of contact.

I have started using thermal grease on the probe/thermowell in my RIMS system and noticed a more accurate response from the controller. I’m not saying it’s necessary but works for me so I’m sticking with it for the time being.

I have some now so will be making use of it anyway :)
