The integrity of the instrumentation cables is an important performance parameter in addition to the sealing performance in a brazing process. An accurate brazing control was developed for the brazing of the instrumentation feedthrough in a vacuum induction brazing system in this paper. The experimental results show that the accurate brazing temperature control performance is achieved by the developed control scheme. Consequently, the sealing performances of the instrumentation feedthrough and the integrities of the instrumentation cables were satisfied after brazing.
