Type K mineral insulated thermocouple cable

Thermocouple cable Type Kis the most common thermocouple junction. In general, it has a wide temperature range, it is reliable and economically priced. The temperature range of type K, NiCr-Ni thermocouples is -270°C ..+1260°C.

Kamet sells the well-known high quality Okazaki’s mineral insulated cable AerOpak®cable. AerOpak® is designed to withstand high pressure and can be used for a wide temperature range from -270ºC to 1260ºC.

Thermocouple cable type K is suited to a wide range of applications some examples include:

  • incinerators
  • furnaces
  • power plants
  • oil rigs
  • heat treatments
  • medical devices

This product offers a range of diameters from 0.25 mm to 12.7 mm. Common applications involve its use with stainless steels, Inconel, and Pyrosil sheaths. You can find more information about the typical sheath materials used for mineral-insulated cables here.

In short:

  • guaranteed tolerance IEC EN60584 class 1, ASTM E230 special limits or AMS2750 E
  • supplied with a 3.1 certificate
  • all raw material used in this cable is from European or Japan origin
  • is deliverd as coil. It can be ordered in straight lengths. These straight lengths will have a bow or curvature.
  • can be bent around a mandrel having a radius equal to twice the sheath diameter without rupturing sheath or causing loss of insulation resistance.
  • the sheath can be welded, brazed and soldered without changing insulation resistance using normal care for the metals and thickness involved.
