My first post after extensive Googling. I'm qualified as an elctronics engineer (retired) Posting this question here in hopes that an enquiring electrcian will know the answer. The last time I changed a tank stat, I disasembled the old one and kept the 18" brass tube and central steel thin rod.. ( I do things like that a lot) I can see how it works but wonder if anyone here knows if that central thin rod is plain steel or Invar..
I have a use for a thin Invar rod in a DIY clock.. Thanks..
