What are you saying here?? No kiln that I know of that has both controller
and kiln setter with limit timer!
But then there are the wonderful pyrometers you can use as a back up, placed
in the middle peep hole to double check temp....within what 10-15 degrees of
so?
hope things are moving along for you Bruce?

Hi Arnold,
I think the chances of an over fire with a controller are fairly rare but to
put a kiln sitter with a timer into the equation I would say almost negate
the possibility of an over fire. The problem I seem to run into is an under
fire. If you do not have cones to visually see then I think this becomes an
issue to be somewhat concerned with. I clearly understand that an over fire
causes irreversible damage and that one can "usually" re-fire an under fired
kiln load.
best of the best,

Several companies will put backup kiln sitters on computers with electronic
controllers. I'm not personally convinced whether this is a good idea or
not; I was talking to a kiln tech once and he agreed that more people
mis-fire this way than prevent a meltdown. (Mis-fire meaning the kiln
sitter would turn the kiln off too early.) But if you always put a higher
cone in the kiln sitter it seems that it would function adequately as a
safety shutoff. And while kilns typically don't cause excessive damage
even if overfired, there is obviously risk, and I'm sure I am not the only
one who has left a kiln running when they are not around...
