Extend Your Thermocouple Reach

Thermocouples are often installed far from the control room, requiring a reliable method to transmit the signal back to the instrument system. Our thermocouple lead wire is designed for this purpose. It extends the thermocouple circuit from the measurement point to the instrument or DCS system by continuing the thermoelectric characteristics of the thermocouple type. This ensures that the temperature signal remains accurate over long distances.

Accuracy and Protection Combined

We use carefully selected thermocouple alloy combinations matched to each thermocouple type. For K-type applications, nickel-chromium and nickel-silicon-based compensation alloys are used to maintain consistent thermoelectric performance. The alloy composition is tightly controlled to ensure stable signal transmission across the full operating temperature range.

To protect the signal in industrial environments, shielding options are available. Aluminum foil shielding provides protection against high-frequency electromagnetic interference, while copper braid shielding is effective against low-frequency magnetic interference. These options help maintain signal stability in environments with VFDs, motors, and other industrial equipment.

A range of jacket materials is also available. Flame-retardant PVC is suitable for general indoor applications, while fluoroplastic insulation is designed for high-temperature and chemically aggressive environments.

Mature Production Process

We have been manufacturing specialty cables since 2018, with thermocouple and compensating wires among our core product lines. Our production process is well established and strictly controlled. Each batch of conductor material is tested for thermoelectric performance accuracy before production.

Our products comply with IEC 60584-3 and GB/T 4989 standards and are CE certified. For export shipments, we provide complete test reports and customs documentation. Common models such as KX, KC, SC, and TX are available from stock for fast delivery.

Frequently Asked Questions

Q: What happens if I use the wrong calibration type, such as using a T-type wire on a K-type system?

A: Using mismatched thermocouple wire will result in significant measurement error because different thermocouple types have distinct thermoelectric characteristics. This can lead to deviations of tens or even hundreds of degrees. It is essential to confirm the thermocouple type before selection. To avoid errors, we verify the model with customers before shipment. If you are uncertain, you can provide a photo or model number, and we will assist in identifying the correct wire type.

Q: What is your minimum order quantity?

A: Our standard minimum order quantity is 100 meters for most models. However, for maintenance, replacement, or small-scale projects, we can also accommodate smaller quantities upon request. We remain flexible to support different project requirements. Please contact our sales team, and we will provide a suitable solution based on your actual needs.
