Aircraft Engine Manufacturer Reduces Scrap With Correct Thermocouples


A manufacturer of commercial and military turbine engines required thermocouple durability and accuracy for correct process control. To prolong the life and reliability of turbine engines, a manufacturer heat treats specialty alloy components.

Heat treating is performed in vacuum furnaces at temperatures in excess of 1800°F (980°C). The manufacturer was particularly concerned with thermocouple drift and insulation integrity as they pertain to producing good parts.


Watlow worked with this manufacturer to establish test methods and parameters along with qualification tests for pass/fail limits. Through the proper selection of materials and insulating methods, the manufacturer was able to assure that correct heat treatment controls were maintained, while reducing the number of non-conforming components produced.
