Product Description:

Core application of thermocouple extension wire (compensating wire)
In one sentence: Pull the cold end of the thermocouple from the high-temperature equipment to a location with stable temperature and suitable for temperature measurement instruments, ensuring accurate temperature measurement and no additional temperature difference errors.
1, Main function
Extend the temperature measurement signal and relocate the working end of the cold junction thermocouple to a high-temperature site. The cold junction should not be placed in a location with high temperature/large temperature fluctuations; Use extension wires to pull the cold end to the constant temperature area of the control room and instrument cabinet over a long distance.
Compensate for thermoelectric potential, eliminate temperature measurement errors, extend the wire material to match the thermoelectric characteristics of the corresponding thermocouple. Within a certain temperature range, it can effectively extend the thermocouple without generating additional parasitic potential, ensuring accurate temperature readings.
The special precious metals for cost saving thermocouples (platinum rhodium, nickel chromium silicon, etc.) are very expensive. Short thermocouple wires are used in the front end, and cheap extension wires are used for long distances in the back, which greatly saves money.
Anti interference, easy to wire specialized compensating wire with insulation and shielding, suitable for workshop bridge and pipeline laying, anti electromagnetic interference, stable signal transmission.
Adapt the instrument wiring to lead the on-site high-temperature probe to the temperature control meter, recorder, and PLC temperature module in a standardized manner, with unified and orderly wiring.

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.
