Thermocouples - Swaged or MGO Assemblies

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. A grounded junction is standard for quick response.

Hex Fitting (HX) Swaged thermocouple with a hex fitting ( HX ) are used where a 316 stainless steel 1/2” x 1/2” NPT fitting is desirable for mounting to the process and to the connection head. The hex fittings are welded to the sheath for strength and proper seating. Other size Hex Fittings are also available—consult factory. 2” bare leads are standard.

Hex Fitting (HX) and Standard Head (Aluminum) (SH) Swaged thermocouple with a hex fitting ( HX ) are used where a 316 stainless steel 1/2” x 1/2” NPT fitting is desirable for mounting to the process and to the connection head. The hex fittings are welded to the sheath for strength and proper seating. These assemblies come with our ( SH ) Standard Heads.

Two Compression Fittings (CF) and

3 Standard Head (Aluminum) (SH) A Compression Fitting ( CF ) is used to mount the Head instead of a hex fitting. These assemblies come with a ( SH ) Standard Head. A second 1/8” NPT 316 stainless steel compression fitting ( CF ) is added by the “ CF ” at the end of the part number to allow for adjusting the depth of insertion. Transition Fitting (TF) These assemblies have extension wire attached to the thermocouple. This is beneficial when the instrument is located some distance from the area where the temperature is being measured. A relief Spring ( SR ) is installed to give protection to the potted junction. 3” of split leads are standard. A 316 stainless steel compression fitting ( CF ) allows for adjusting the depth of insertion. 5 Transition Fittings (TR) and Armored Cable (AC) These assemblies are the same as the ones above but with a some length ( Z ) of Armored Cable on the extension wire. 4
