The kiln sitter is a crucial component in pottery kilns. It is designed to automatically control the firing process by sensing the temperature inside the kiln.
5 Key Components of a Kiln Sitter Explained
1. Tube Assembly
The tube assembly is the central part of the kiln sitter.
It houses the cone supports and the sensing rod.
This allows them to move in response to changes in temperature.
The tube assembly is usually made of a high-temperature-resistant material.
This is to withstand the extreme conditions inside the kiln.
2. Cone Supports
Cone supports are designed to hold temperature-indicating cones (also known as pyrometric cones) in place.
These cones are calibrated to bend or fall over at specific temperatures.
This signals the kiln sitter to take action.
Cone supports are positioned within the tube assembly.
This ensures that the cones are correctly aligned to react to the temperature changes.
3. Sensing Rod
The sensing rod is a critical part of the kiln sitter.
It directly interacts with the cone supports.
When the cones fall over due to reaching their designated temperature, the sensing rod is moved.
This then triggers the kiln to shut off or adjust its firing cycle.
The movement of the sensing rod is typically connected to the kiln’s electrical system.
This allows it to control the power supply to the heating elements.
4. Optional Timer
Some kiln sitters come with an integrated timer.
This can be used to control the duration of the firing cycle independently of the temperature-based controls.
This feature is particularly useful for ensuring that the firing process adheres to a predetermined schedule.
It provides an additional layer of control over the kiln operation.
5. Replacement and Customization
Kiln sitters are designed in a modular fashion.
This allows individual components to be replaced as needed.
This is particularly beneficial for maintaining older kilns.
It allows for partial upgrades without the need to replace the entire kiln sitter system.
The availability of kiln sitters with or without a timer offers flexibility.
This helps in choosing a system that best fits the specific needs and operational preferences of the user.
In summary, the kiln sitter is a sophisticated yet essential component in pottery kilns.
It enables precise and automated control of the firing process.
Its design allows for a high degree of reliability and adaptability.
This makes it a valuable tool for ceramic artists and manufacturers alike.
