The Dawson Kiln Sitter is a mechanical devise which removes power from the heating elements when cone is achieved.

Supplied as standard equipment on all Classic, TnB and Fyrematic series kilns (save a few smaller models).

See below for further discussion

A Kiln Sitter is a mechanical devise which removes power to the heating elements once the proper cone has been reached. The user sets a small pyrometric cone into the Kiln Sitter and proceeds to fire the kiln. When the proper amount of "heatwork" is done the cone will have deformed, thereby releasing the mechanical action which then removes power to the heating elements.
 

What Kilns Use a Kiln Sitter?

Currently, Evenheat produces three series' of kilns which include the Kiln Sitter as standard equipment: Classic, TnB and Fyrematic. In each of these series' the kilns contain controls which regulate and control the heat with the Kiln Sitter shutting off power to the elements at the proper time.
 

Does the Kiln Sitter Control the Heating?

No. The Kiln Sitter simply removes power from the heating elements when proper cone is achieved. It has no other function.
 

What is the Limit Timer For?

The Kiln Sitter contains a devise known as a Limit Timer (round knob shown above on Kiln Sitter faceplate). The role of the limit timer is to remove power from the elements after a certain period of time. This is what may be called a "back up" in the event of Kiln Sitter failure. The limit timer should never remove power during normal operation.
 

Can I Use any Pyrometric Cone in the Kiln Sitter?

No. Only those cone designed for use in the Kiln Sitter should be used.
