This is a Type T (Constantan/Copper) Feedthrough Thermocouple incorporating 5 pairs of non-magnetic conductors with screw type connections. Constantan (a copper-nickel alloy) is used for the negative conductors with longer vacuum side ends. OFHC Copper is used for the positive conductors and the vacuum side ends are shorter. This thermocouple feedthrough uses a KF-40 (2.16" diameter) vacuum flange which provides a Leak Rate of Thermocouple is the description for electrical feedthroughs that are commonly used for temperature measurement systems. A thermocouple feedthrough does not measure temperature, but rather it is used to conduct the thermocouple’s voltage signal from inside the vacuum system to an external instrumentation device. These feedthroughs use ceramic to metal sealing technology to braze various metals used in thermocouple assemblies to high purity alumina ceramic insulators. Thermocouple feedthroughs are suitable for ultra high vacuum applications. Several mounting options are available, being Weld On, KF, CF, Baseplate and NPT Adapters.
