| G-GROUNDED JUNCTION |
The conductors
and sheath material are simultaneously cap welded. This process
forms a measuring junction which is an integral part of the
end cap and electrically grounded to the sheath. The most common
junction style, grounded junctions protect the thermocouple
conductors from contamination and offer fast response times.

| R-REMOTE OR UNGROUNDED JUNCTION |
The conductors are the
first junction welded together. Prior to cap welding the sheath
the junction is covered with insulating material to insulate
it from the sheath and end cap. Remote junctions protect the
thermocouple conductors from both contamination and outside
electrical interference. They are used whenever electrical isolation
of the element is desireable.

| E-EXPOSED JUNCTION |
The sheath material is stripped back slightly and the conductors are welded together to form a measuring junction. The exposed insulation is sealed against moisture penetration. Exposed junctions provide the fastest possible response times but offer no protection to the thermocouple's conductors.

| *When ordering dual element
remote or exposed junctions a "C" indicates common
junction (all four conductors welded together forming a common
junction); an "S" indicates separate junctions (each
thermocouple element independently separate and isolated from
each other). |
