Swaged or MGO thermocouples have a metal sheath and compacted
Magnesium Oxide powder for insulation. Since they have ceramic
insulation, swaged thermocouples can go to a much higher temperature
than Miniature and Probe types.
Swaged thermocouples are very
flexible and can safely handle a bend around a surface two times
the diameter of the sheath.
!
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
” to the part number.
Example: 18K4DS9-G-K1-*
Swaged thermocouples are also available in Types B, C, R, and S.
Sheath materials other than the common ones listed at the bottom of
this page can be ordered. Some of these include: Molybdenum,
Tantalum, or Hastelloy. Phone one of our sales engineers for details.
We understand how important the quality of our thermocouples is to
our customers. This is why our thermocouples are made with high
purity Magnesium Oxide insulation and conductors which are within
special limits of error.

Swaged or MGO, Male Plug
Swaged thermocouple with a standard size plug. The plug is constructed with
solid
pins. We do not sacrifice quality by selling plugs with hollow pins.
A 1/8” NPT 316 stainless steel compression fitting (
CF
) can also be specified
by adding “
CF
” to the end of the part number. A grounded junction is standard
for rapid temperature response.

Swaged or MGO, Female Jack
Swaged thermocouples typically have a male plug installed on the sheath, but
are available with standard size female jack option. A 1/8” NPT 316 stainless
steel compression fitting (
CF
) can also be specified by adding “
CF
” to the end
of the part number. A grounded junction is standard for rapid temperature

Swaged or MGO, Open Terminal (OTH)
Swaged open terminal block assemblies can be exposed for easy access.
They are useful in situations where a low profile is needed. The terminal block
is ceramic for maximum heat resistance. A 1/8” NPT 316 stainless steel
compression fitting (
CF
) can also be specified by adding “
CF
” to the end of the
part number. A grounded junction is standard
