FAQ

Q: What is a K Type Thermocouple Compensating Cable?

A: A K Type Thermocouple Compensating Cable is a specialized cable used to connect K-type thermocouples with temperature measuring instruments. It uses matching compensating conductors to help maintain measurement accuracy.

Q: Why is a compensating cable needed for thermocouples?

A: A compensating cable helps maintain the thermoelectric characteristics of the thermocouple circuit and reduces measurement errors caused by unsuitable connection wires.

Q: What is the difference between KX and KC compensating cables?

A: KX cables use conductors with characteristics closer to K-type thermocouple materials and are commonly used for higher accuracy requirements. KC cables are generally used for shorter-distance compensation applications.

Q: What insulation materials are available?

A: Available insulation materials include PVC, PTFE, FEP, fiberglass, and silicone rubber, depending on temperature and environmental requirements.

Q: Can shielding be added to the cable?

A: Yes. Aluminum foil or tinned copper braid shielding can be added for applications requiring improved electromagnetic interference protection.

Q: What temperature range can this cable withstand?

A: The operating temperature depends on insulation and sheath materials. PVC versions typically support up to 200°C, while FEP and fiberglass constructions can support higher temperatures.

Q: Can the cable be customized?

A: Yes. We can customize conductor type, core number, insulation material, shielding, sheath, color coding, and cable length according to customer requirements.

Q: Which standards does the cable comply with?

A: The cable can be manufactured according to IEC 60584-3 and ANSI MC96.1 standards.

Q: What is the MOQ and lead time?

A: The typical MOQ is 500–1000 meters per specification. Standard products are usually delivered within 7–15 working days, while customized products may require additional production time.

Q: How do I select the right compensating cable?

A: Selection depends on thermocouple type, operating temperature, installation environment, required accuracy, shielding requirements, and connection distance. Our technical team can recommend a suitable solution.
