Thermocouples: Function, Types, Selection and Application

The type of probe thermocouple depended on the temperature range we expected to see within the chamber and since the temperature within the chamber is a known in this case it was 1100°C we were then able to refer back to the table of thermocouples to find a thermocouple that has a temperature range that includes that temperature. In this case we chose a Ktype thermocouple.
