The Bridge Between Thermocouples and Instruments

Accurate temperature measurement depends on signal integrity across the entire measurement loop. A thermocouple generates a signal at the hot junction, while the connection point at the instrument forms the cold junction. Our compensating wire connects these two points and helps ensure accurate signal transmission. It provides thermoelectric characteristics matched to the thermocouple type, helping reduce cold junction errors and improve measurement accuracy.

Alloy Conductors for Accurate Matching

The key lies in carefully selected alloy conductors. We use materials with thermoelectric characteristics matched to specific thermocouple types. For example, in K-type systems, matched compensation alloys are used to replicate the thermoelectric behavior of the thermocouple circuit. This matching is critical-incorrect wiring can lead to significant measurement deviation. With years of production experience, we ensure stable and consistent performance for K, S, T, and other common thermocouple types.

Options for Different Industrial Environments

We offer a variety of insulation materials to suit different operating conditions. PVC insulation is suitable for normal environments up to 105°C. For higher-temperature applications such as boilers or heat pipelines, XLPE or fluoroplastic insulation is available, with temperature resistance up to 200°C or higher.

Shielding options are also available, including aluminum foil and copper braid shielding. These help reduce electromagnetic interference (EMI) from surrounding equipment and improve signal stability in low-voltage temperature measurement systems.

Our production process follows strict quality control standards. Each batch is tested for thermoelectric performance accuracy. The products comply with GB/T 4989 and IEC 60584-3 standards. Common models such as KX, KC, SX, SC, JX, JC, TX, and TC are available from stock. Custom lengths and configurations are also supported.

Frequently Asked Questions

Q: What is the difference between compensating wire and extension wire?

A: A compensating wire uses alloy conductors with thermoelectric characteristics matched to the thermocouple type, typically used in moderate temperature ranges and offering a more cost-effective solution. An extension wire is manufactured using the same materials as the thermocouple itself and is suitable for full temperature range applications with higher accuracy. In most industrial installations, compensating wire is sufficient to meet measurement accuracy requirements while reducing cost. We can recommend the appropriate type based on your thermocouple system and operating conditions.

Q: Can this wire handle high temperatures?

A: Temperature resistance depends on the insulation material. PVC insulation is suitable for -20°C to 105°C. For higher-temperature environments such as boilers or hot ducts, XLPE or fluoroplastic insulation is recommended, with temperature resistance up to 200°C or higher. Please provide your operating conditions, and we will recommend the most suitable insulation system for your application.
