The idea that *WHEN* the filaments melt the sensors operate make me think of the idiot lights in cars now that go on only when there is a problem ie; oil light comes on when you have run out of oil pressure (as well as oil) with out warning. I'm sure that the engine filaments we speak of here are not like that. (?) Are they,...........

No, they are not so abrupt as I may have implied; my apologies for that. They do actually provide temperature readings.
