WHY PROTECTED THERMOCOUPLES?
- The Protection Tube extends past the tip, protecting the tip from damage while loading the kiln
- Keeps the oxide dust from the thermocouple tip from getting into the kiln while firing.
(Any dust should still be vacuumed when doing the normal cleaning of the kiln).
- Protects thermocouples from excessive radiation error from the nearby hot elements.
- Reduces zone control errors because the tips of all thermocouples are equally exposed to the heat of the kiln while still being as protected as possible.
Size and Description
- The protection tubes are 3/4” in outside diameter with a 1/2” inside diameter (which accommodates the standard 8 gauge Type K thermocouple).
- There is a flange on the back end of the thermocouple to prevent it from going into the kiln.
- The tube is open but protrudes past the delicate tip of the thermocouple.
Calibrating the Kiln
- For ceramic work we recommend calibrating the kiln performance with cones and adjusting the control to match the performance of the firing cones. The most important thing is to get a consistent reading from the thermocouples.
