Metal Sheathed Mineral Insulated RTD Cable for Temperature Detecting, also called RTD MIC, compose of copper or Nickel signal wire conductors and stainless steel or Inconel outer metal sheath. The mineral normally known as compact magnesium oxide are filled between the space of nearby conductor lead wires. There are several choices for the core numbers such as 2 ,3 , 4 or 6 showing the number of wire internal conductors.

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.
