Thanks Wade, from these posts I have worked out the positions for the thermocouples. I am still not clear whether they need some sort of tube around them and what are the temperature ranges.

I guess I'll go with the glass bead Omega ones with 2m wires. And if I find some teflon tube lying around, I'll use that to shield the business ends. They should work up to 450 deg C, which judging from what I have seen here should do inside the bricks and further out. Will someone correct me if I am wrong?

I'll try to get them in for the floor at an early stage (before pouring the support slab). Incorporating some into the dome should be easier. I am tempted not to drill the dome but to squeeze the probes between the elements/bricks.

Is this a good plan?

Cheers,
W.
