Abstract: A potassium nitrate level detection sensing module M in a strengthening furnace according to the present invention includes a level detection means, which is installed inside a glass strengthening furnace, installed at a height equal to a level line of strengthening liquid to be filled in the strengthening furnace F, and generates an electrical signal having a set threshold or more or an electrical signal having the set threshold or less when it comes into contact with the strengthening liquid and detects that the strengthening liquid filled in the glass strengthening furnace F has reached a set strengthening liquid level line. The potassium nitrate level detection sensing module in the strengthening furnace according to the present invention having such a configuration can automatically identify that potassium nitrate in a liquid state, which is melted in the strengthening furnace, has reached the set level line in the strengthening furnace.
