Example:
The part number describes the thermocouple giving the gauge,
type of wire, construction, tube length and mounting device, if any. The part number
8K4-1012XH-24-AF
signifies an 8 gauge, Type K complete assembly, 1/2” NPT extra
heavy 24” long #10 alloy (32% nickel - 215 chromium) tube, a 1/2” Adjustable Flange
and a screw cover head. Other combinations of thermocouples and tubes can be speci-
fied depending on your application.
!
Note:
If you would like to order a Type E, J, or N assembly, just substitute the “
J
”
with an E, J, or N in the part numbers listed on this page.
