Thermocouple Assemblies with
T3/T4 Leadwire Termination and Support Tube

 

 

T3/T4 Assembly
An adjustable support tube offers flexibility for immersion adjustment while protecting the sheath
from potential damage during installation. The rigid, thick wall offers additional support when
penetrating the vessel/furnace wall.
This exclusive Conax Buffalo design provides a practically unbreakable connection between
the leadwire and probe lead. The T3 epoxy-filled transition is supplied with Teflon-insulated
extension wire as standard; silicone-impregnated fiberglass insulation is also available.
Standard extension end leads are 24" long (longer leads available on request). When the
progressive description specifies 24 gauge probe wire, 20 gauge extension wire is standard.
When the progressive description specifies 30 gauge probe wire, 24 gauge extension wire is
standard. T4 termination provides a stainless steel overbraid for maximum
flexibility and abrasion resistance. Available in all sheath materials
and wire types. Both termination types function
to 300˚ F (150˚ C) continuous temperature.
