Kiln Thermocouples For High Temperature
The temperature measuring probes that protrude into your kiln chamber and send information to your controller are known as thermocouples. They, like elements, can deteriorate with time.
The length of time they will endure is determined by the temperatures you are firing at and the number of combustibles they are exposed to. If you just use your kiln for glass fusing (between 1400 and 1500 degrees Fahrenheit), you may never need to update your thermocouple. You might only get 20 firings out of a cone 10 crystal glaze if you hold it at high temperatures (above 1800 F).
There are many different types of thermocouples but the standard is the Type K. Check with your dealer or manufacturer to be sure which one you have before you order your replacement.
