Copper Conductor Mineral Insulated Thermocouple Cable of Metal
Sheath is extruded into shape, made of two different metal
conductors and inorganic mineral insulated material.
Features
Specification
Take the KSK2B30 as example to explain the specification
Example | K | S | K | 2 | B | 30 |
KSK2B30 | K=thermocouple cable | Sheath material | Conductor Combinations | Number of Conductors | EMF Characteristics | Sheath Diameter (mm)ⅹ10 |
Thermocouple Precision Grade
The EMF thermocouple output and tolerance are met with products
covered in this specification and are certified at a given
temperature.
Conductor Combination Reference | Calibration Temperatures ℃ | Tolerances | |
J | 200 400 700 | Grade 1 | Grade 2 |
K&N | 200 400 600 800 1000 | -40℃ to 375℃ within ±1.5℃ | --40℃ to 333℃ within ±2.5℃ |
E | 200 400 600 800 | -40℃ to 375℃ within ±1.5℃ | -40℃ to 333℃ within ±2.5℃ |
T | 200 400 | -40℃ to 125℃ within ±1.5℃ | -40℃ to 133℃ within ±2.5℃ |
Note: the maximum calibration temperature should not exceed the
maximum continuous operation temperature of the sheath material.

Quality Inspection
When product manufacture is finished, every coil of cable should
undergo a series of quality assurance tests.
1 Sheath integrity (water immersion test)
2 Dimensional tolerances
3 Surface finish
4 EMF calibration
5 Insulation resistance
6 Sheath ductility
7 Conductor ductility
Testing report is available upon request. Additional specialty
tests can be arranged as per customer’s requirement.
