K-Type Thermocouple Compensation Wire Product Features and Applications

PVC-insulated and sheathed compensating conductors or cables offer excellent moisture resistance, wear resistance, and flame retardancy; thermally-resistant plastic-insulated and sheathed compensating conductors or cables, utilizing continuous extrusion technology, boast superior properties such as high-temperature resistance, cold resistance, resistance to acids, alkalis, oil, and water, non-flammability, and anti-aging.

The intrinsic safety explosion-proof temperature measurement system utilizes compensation wires or cables with a low capacitance and low inductance material structure, featuring explosion-proof safety performance. It is suitable for connecting explosion-proof thermocouples and temperature measurement instruments in environments with explosion hazards, thereby forming an intrinsically safe thermocouple temperature measurement system.

K-Type Thermocouple Compensation Wire Product Execution Standard

GB/T 4989-94 (equivalent to IEC 584-3 standard)

Three: Characteristics of K-Type Thermocouple Compensation Wire

Conductor Maximum Working Temperature: Thermal Resistance Grade: Polyallene*Propylene (F46) 200°C

Soluble Poly(tetrafluoroethylene) at 260°C

Silicone rubber at 180℃

Standard Grade: Polyvinyl Chloride at 70℃ and 105℃, Cross-linked Polyethylene at 90℃

Low-smoke, halogen-free flame-retardant polyolefins at 70°C, crosslinked at 90°C and 125°C

2. Low Environmental Temperature: Polyvinyl Chloride (PVC) Sheath: Fixed installation -40°C, Non-fixed installation -15°C

* Plastic Insulation and Sheathing: Fixed installation -60°C, Non-fixed installation -20°C

3. Cable Bend Radius Allowance: Unarmored cable has a minimum bend radius of 6 times its outer diameter.

Copper tape shielding or steel tape armor is 12 times the diameter of the cable.

*The plastic insulation and sheath are 10 times smaller than the cable's outer diameter.
