Thermocouples -Swaged or MgO Elements

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 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. this page. Double element assemblies are also available. Add a ” D ” to the part number. Example: 18K4DS9-G-K1-*
