Thermocouple Extension Assemblies
Selection of thermocouple heads is made on the basis
of operational requirements, accessibility, and/or the
need to avoid direct contact with hot surfaces. Also,
it is often required that the extension permit removal
of the thermocouple element. For these requirements,
NEWPORT offers a complete line of configurations and
component parts which can be configured for specific
applications. NEWPORT® extensions are made of 1/2" NPT
standard weight galvanized steel nipples and unions.
