Note:
If you would like to order a Type E, J, N, or Type T assembly, just substitute the “
K
“ with a “
E
“, “
J
“, “
N
“, or “
T
” in the part numbers
listed on this page. Double element assemblies are also available. Add a ”
D

Probe, Bayonet Fitting
Standard plain Bayonet Fitting probe. Specify : “
X
” overall length, and “
Y
”
probe sheath length. Specify “
U
” Length for location of Bayonet Fitting on
probe. If it is at the tip of the hot end then “
U
” = 2 (2 inches).

Probe, Bayonet Fitting
Overbraided OB8 = 304SS OB9 = Alloy 9 (600)
The overbraid is on the exposed insulated wire portion of the probe - from
the sheath to the cold end. It is used to protect the insulation from abrasion
and to help shield against electrical pick up.

Probe, Bayonet Fitting, Plug & Jack (K3)
A Quick disconnect Plug and Jack (
K3
)
is added to the assembly. Removing
(K3) and substituting a (
K1
) would be a Plug only,. Substituting a (
K2
) would
be a Jack only.

Probe, Angle, Bayonet Fitting
90 degree and 45 degree angel are standard, but other angels can be or-
dered. The part numbers shown are for 45 degree probes. For 90 degree,
change the “45” to “90” in the part number. For the optional Relief Spring
(
SR
) add “

Thermocouple Probes have a maximum service temperature of 1300°F (700°C) depending on the type and gauge of the
thermocouple wire used in their construction. The Bayonet Fitting presets the depth and allows quick attachment and removal. The
elements are made with impregnated fiberglass wire. The 30 gauge 1/16” O.D. probes have a high temperature limit of 400°F (200°C)
due to Kapton insulation on the element. A grounded junction is standard to help prevent the element from pulling out of the tube
and to provide a rapid temperature response time.
#9 Alloy (600) is standard, but other alloys such as: #7 (446SS), #8 (304SS), *16 (316SS), Hastelloy C etc. are also available.
See listings under “Miniature Metal Protection Tubes. Just replace the “9” in the part number with the desired alloy.
