kiln-sitter on gas?

I've long wondered if it is possible to install a kiln-sitter on a gas
kiln. Although it wouldn't be able to turn off the gas burner, it would
be much easier to see when the cone is bent. Has anyone ever done this?

Actually it could cut the gas off and very simple too! the kiln setter could
trip a solenoid to the main gas valve. The kiln setter trips a switch that
opens the circut to the kiln, just have it trip the solenoid that controls
the main gas burner. WWW Graingers has all the neat stuff for do it
yourselfers like myself. Great Idea! keep them brain storms a brew'in!!
Good luck!

I have a small Alpine gas kiln which came complete with pyrometer and
kiln-sitter. The kiln -sitter when operated holds an electric solenoid valve
open in the gas supply line, when it drops it releases the valve shutting
off the gas supply. Not very reliable re temperature due to uneven heat in
kiln, better to go by visual cones on different shelves.......

Joanne,
I have wondered the same thing, but I have considered having a solenoid
valve on the main gas line, which the sitter would cause to close. I know
that isn't the "double block and bleed" setup with Maxon valves in a
commercial gas kiln, but I wonder if it would work and be safe? I too
wonder if anyone has experience with such an approach.

Joanne,

I see no reason why a kiln sitter wouldn't work on a gas kiln, in fact, you
could have your gas fitter fit a gas solenoid to the line, and the kiln
sitter could turn off the kiln - of course you couldn't soak at all. You
would have to select the location carefully to avoid direct flame, of
course.

Sure, this is done all the time and it does indeed turn off the burner. A
pyrometer with a switch (controller) is attached to the kiln. The controller
then runs to a solenoid on the gas line. You reach a preset temperature and
the solenoid closes a valve that shuts off the gas. That's the simple answer.
There are other complicated issues like ramps, non latching relays, fuzzy
logic, standing pilots, ect. that are better discussed on the phone. Like any
shutoff though, these guys are meant as backups to YOU turning everything
off. We build a controller like this or you can use an electric kiln
controller (120V), hooked to a solenoid (120V), with a standing pilot system.

The main problem I see with this idea and also the programmable controller on my
Geil
kiln is that if you are firing with gas, you are usually firing reduction high
fire. Fine the kiln setter turns off the gas, you aren't around. The damper
stays open........
I could see putting a kiln setter in the door or wall so that when it tripped
itself you had reached a particular cone, but I sure wouldn't have it turn off
the gas.
With Geil's program you can ramp the temp, but as soon as you mess with the
damper, and I know from experience that moving the damper 1/16th to an 1/8th of
an inch can make the difference between a stall and temperature climb, then all
bets are off. Never figured out how to use the ramp control, I set it on high
limit and manually fire.

Joanne,
My gas kiln at school where I teach has a kiln setter on it .It shuts
the main gas valve off but leaves the pilot burners on, I'm always there
at the shut-off and shut all the valves off and close the damper before
I leave. The only problem is the setter is directly above one of the
burner ports! The acuracy isn't all that great but you can adjust by
changing the cones, higher or lower. Also NO peep holes! Go figure. Mike
