K T N S Type Thermocouple Wire 2 Cores PTFE Insulator Shielded Line High Temperature Measuring Compensation Cable

K T N S Type Thermocouple Wire 2 Cores PTFE Insulator Shielded Line High Temperature Measuring Compensation Cable

Product Description:

The function of compensating wires for thermocouples is to extend the thermoelectric electrode, that is, to move the cold end of the thermocouple and connect it with the display instrument to form a temperature measurement system.

Here are its key features and selection considerations:

Core Features and Applications:

1.Signal Transmission: Accurately transmits the millivolt-level thermoelectric potential signal generated by the thermocouple at the measurement point.

2.Extension and Compensation: Replaces expensive K-type thermocouple wires (positive electrode: nickel-chromium, negative electrode: nickel-silicon) for long-distance laying, and extends the thermocouple's "cold junction" (reference junction) from the high-temperature field to the temperature-stable control room, enabling accurate cold junction compensation in instruments.

3. Cost-Effectiveness: Uses inexpensive alloy wires that match the thermocouple's thermoelectric characteristics, significantly reducing wiring costs.

Extension Cables vs. Compensating Wires:

Extension Cables: The conductor alloy is exactly the same as the corresponding thermocouple (e.g., KX), maintaining high accuracy over a wider temperature range (e.g., -40°C to 200°C), but at a higher cost.

Compensating Wires: The conductor alloy is different from the thermocouple but has matching thermoelectric properties (e.g., KCA/KCB), guaranteeing accuracy only within a limited temperature range (e.g., 0-100°C), and at a lower cost.

General Terminology: In practical applications, "extension cable" is often used as a general term for both.

For most industrial applications, compensating wires are sufficient.

Conductor materials:

Thermocouple cables come in several variations, primarily distinguished by their insulation materials and construction to suit different environmental conditions and applications.

Here are the main types:

1. PVC Insulated: Suitable for general-purpose applications with moderate temperature ranges.
2. Fiberglass Insulated: Used for higher temperature applications, offering better heat resistance.
3. PTFE Insulated: Ideal for applications requiring chemical resistance and flexibility in low to moderate temperatures.
4. Silicone Insulated: Provides good flexibility and heat resistance, often used in high-temperature environments.
5. Mineral Insulated (MI): Features a metal sheath with magnesium oxide insulation, suitable for high temperatures, harsh environments, and where mechanical protection is needed.

Each type is chosen based on specific operational requirements, such as temperature range, chemical exposure, and mechanical durability.
