I am constructing a temperature control chamber. Of course, thermal insulation, is key in the development of the chamber. The idea is to insert different electronic circuits inside and study their response in temperature.
The problem which we are dealing with right now, is to decide how the cables will pass to the electronics inside the chamber to the outside. Naturally, the idea is to do this passage with the least possible insulation lost. I was thinking about a rubber grommet, or something that will adapt its shape to what´s passing through.
What is a good way to route cables through insulation?
