Type J K Mineral Insulated Thermocouple Cable
Mineral insulated cable from Shenglong is ideally suited to solve many difficult applications. The mineral insulation available provides excellent high temperature dielectric strength to ensure signals are carried faithfully to the instrumentation or controls.The outer sheath can be made using any malleable metal in a wide range of diameters containing single or multiple wires. Easily formed or bent, it can accommodate virtually any configuration. The outer sheath protects the thermocouple or thermocouple extension wires from oxidation and hostile environments that quickly destroy unprotected wire. Available insulation provides excellent high temperature dielectric strength to ensure that signals are transmitted to instrumentation or controls.
Feature: 
1). Mineral insulated cables are the industry standard, proven choice for high temperature probe fabrication. 
2). Bulk MI cable is rugged, inexpensive, reliable, widely accepted by industry, and readily available in standard configurations, 
the metal sheath provides a self-armoured cable, which is mechanically robust even at small diameters. 
3). The small mass and high thermal conductivity of a properly made cable promotes rapid response of the finished thermocouple assembly. 
4). Sheath materials can be selected to offer strong resistance against corrosive environments and extremely high temperature 
effects. 
Technique parameter:
Mineral Insulated Material
 
SS304
Maximum temperature: 900°C (1650°F). Most widely used low temperature sheath material. Extensively used in food, beverage, chemical and other industries where corrosion resistance is required. Subject to damaging carbide precipitation in 482°C to 871°C (900° to 1600°F) range. Lowest cost corrosion resistant sheath material available.
 
SS321
Maximum temperature: 871°C (1600°F). Similar to 304 SS except titanium stabilized for intergranular corrosion. This alloy is designed to overcome susceptibility to carbide precipitation in the 482° to 871°C (900° to 1600°F) range. Used in aerospace and chemical applications.
 
SS316
Maximum temperature: 900°C (1650°F). Best corrosion resistance of the austenitic stainless steel grades. Good corrosion resistance in H2S. Widely used in the food and chemical industry. Subject to damaging carbide precipitation in 482° to 871°C (900° to 1600°F) range.
 
SS310
Maximum temperature: 1150°C (2100°F). Mechanical and corrosion resistance, similar to but better than 304 SS. Very good heat resistance. This alloy contains 25% Cr, 20% Ni. Not as ductile as 304 SS.
 
Inconel 600
Maximum temperature: 1177°C (2150°F) Continuous; 1260°C (2300°F) Intermittent. Similar to Alloy 600 with the addition of aluminum for outstanding oxidation resistance. Designed for high temperature corrosion resistance. This material is good in carburizing environments, and has good creep rupture strength. Do not use in vacuum furnaces! Susceptible to intergranular attack by prolonged heating in 538° to 760°C (1000° to 1400°F) temperature range.
