As pioneers in providing Integral Rigid Thermocouple Assemblies for small to medium power gas turbine engines, Semco Instruments has refined this design configuration to an art form. Thermocouple assemblies can be provided either in a completely rigid, hermetically sealed configuration or in a Semi-Rigid configuration. The semi-rigid configuration combines an integral, multi-point measurement array that transmits the discrete and/or averaged measured temperature signals with flexible, high temperature cabling to meet the most demanding requirements of each application.
