Lessons Learned - Quench Module Insert (QMI) Furnace Type C Thermocouple (TC) Assembly and Testing Lessons Learned
Year: 2005
Abstract: Abstract:
The QMI furnace required custom-designed Type C Thermocouples (TC) to meet the scientific requirements for the hardware. In implementing the custom requirement set and associated verification testing for these TCs notable anomalies/problems were encountered in two areas. The primary problem was the discovery of contamination (mostly Carbon deposits) on the inner surfaces of the TC that led to acceptance test failures. A secondary problem was caused by attempting to maximize the TC wire size yet limiting the overall TC sheath diameter leading to assembly problems of each TC.
