standard assembly consists of an 1/8" O.D. MgO insulated, type
"J" Thermocouple in a Stainless Steel Sheath. The body is
stainless steel with a 1/2" -20UNF-2A thread. A Thermal Barrier
reduces heat transfer from body to Thermocouple. Other parts include
a Packing Seal, Compression Barrel Nut, hex Adjusting Screw, and a
Polarized Quick Disconnect Male Plug. Standard Immersion is adjustable
from flush to 1". Standard body lengths are 3" and 6"
measured from the beginning of wrench flats to the bolt tip.
adjustable Plastic Melt Thermocouple has a movable probe actrivated
by an inner screw mechanism. The probe can be immersed into or withdrawn
from the plastic melt stream while the extruder is in full operation
at maximum flow rates and pressures. This feature permits temperature
measurement at various depths in the melt stream, eliminates thermocouple
breaking at start-up and prevents hang-up. As it is retracted into
the body, any film formed on it is scraped off.
