For high-temperature sheathed thermocouples are senior K type in more than 1000 ℃ sheath has excellent durability and stability under the environment of high temperature thermocouple.
they can significantly decrease the cost of high temperature measurement, we have no choice, only option price Gao Lian platinum thermocouple. We recommend that you use these types of thermocouple. We have already finished the production and sales the MI cable companies in the United States for manufacturing/global exclusive rights ( A monopoly in the United States alone) 。 “ 2300' Says the product is available in 2300 degrees Fahrenheit ( 1,260℃） Under use.
K type sheathed thermocouples feature
1. Excellent durability and stability
because we have adopted a special kind of alloy, metal sheath material at high temperature in the solid oxide film is formed on the metal surface, alloy evolved into the protection. As a result, reduced the sheath of the high temperature oxidation and degradation, prevent the erosion of the external material permeability, and suppress the degassing of the component, in order to obtain the stable output.
2. Longer product life
in the same conditions of environment, the desired product life than traditional stainless steel sheath and Inconel sheathed several times longer.

specification:

standard JIS C1605 - based 1995 normal limit. However, sheath material diameter & phi; 0. 25 and & phi; 0. 5 is equivalent to NCF600 materials.
here use temperature value is based on published documents, internal testing and so on. Therefore, they are not guarantee value.
our NCF600 provides a k type thermocouple sheath inventory.
we don't have in stock all types of element ( Double) 。

K type sheathed thermocouples using note
as a feature of high-temperature sheathed thermocouple alloy used in high temperature when they develop into self-protection alloy, but if in use after bending, is in the sheath surface oxidation film of deformation may occur. Is broken, sheath may be damaged. When they bend before use, don't bend them ten times or more in the sheath diameter and repeated bending in the same position. In addition, because under the environment of high temperature/vacuum will Al components extraction to surface and sheath become fragile, if K type sheathed thermocouples in use after bending, they might be damaged.
we have other special sheathed thermocouples, can be used under the ultra high temperature of 2000 ℃. You can use the atmosphere of product co. , LTD. However, we used the K type thermocouple elements of special material, and use the Ta ( Tantalum) And Mo ( Molybdenum) , they are high melting point metal sheath material, so we can use these products under the ultra high temperature. Please note that, according to the sheath outside diameter, sheath material, composite insulators, such as, we can't support certain products.
