Category: Thermocouple Feedthrough

Thermocouple feedthroughs carry instrumentation signals while providing electrical isolation and hermetic sealing. They are leak free in high and ultra-high vacuum environments and are composed of only inorganic materials.

Thermocouple Feedthroughs are commonly used in temperature measurement systems. They are designed to conduct a thermocouple’s voltage signal from inside the vacuum system to an external controller. They have a hermetic seal between the alumina ceramic and various Thermocouple conductors such as Alumel, Chromel, Iron, Constantan, and compensating wire for Tungsten, Rhenium, Platinum, and Rhodium.
