1939 microvolt potentiometer measurement article

<< < (3/3)


I use this design made by plate cutting (5000 serie alloy )G welding  and no milling , that allow to built boxes on purpose up to quite big boxes without massive costs .

Cover is showed lifted  for clarity

That possible to set two boxes as russian dolls and you can also use several type of material as aluminium alloy for temperature and another boxe ( Russian doll ) in steel ( cheap ) or copper if necessary , but in light alloy or steel the drawing I have linked works without problem except a 10 mm thickness wall box in steel will be quite heavy


I have not seen something so interesting in a very long time
