Thermocouple & PT100 Cables – Compensation and Extension Cables

Thermocouple cables (compensation/extension) are used to carry the sensor signal to the measuring device correctly. PT100/RTD cables are designed for resistance measurement wiring and are commonly used for RTD sensor connections. Correct selection depends on the sensor type, cable cross-section, and insulation/environment.

Compensation vs Extension Cable

• Compensation cable: helps maintain accurate signal transfer within a specified temperature range using type-compatible alloys.
• Extension cable: used to extend the thermocouple line; type compatibility is critical.

Quick Selection Guide

• Sensor: Thermocouple (Type K/J/T/S etc.) or PT100/RTD?
• Cores / wiring: Thermocouples are typically 2-core; PT100 options include 2/3/4-wire.
• Cable cross-section: based on application needs (e.g., 2x0.22 mm²).
• Insulation & outer jacket: chosen according to temperature, abrasion, oils/chemicals, and field conditions.
• Shield/braid (if needed): preferred in noisy environments for better signal stability.
• Length: longer runs may require better protection and appropriate cross-section.

Compatibility Note

For thermocouple cables, type compatibility is essential (Type K cable + Type K circuit). If you’re unsure, share your probe/cable type and we’ll help confirm the correct match.

Price & Quotation Criteria

Thermocouple and PT100 cable prices vary depending on type, cross-section, insulation, shielding/braid and length. For a fast and accurate quote, please share:

1. Thermocouple type (K/J/T/S) or PT100 (2/3/4-wire)
2. Cable cross-section and required length
3. Insulation/jacket preference (temperature and environment)
4. Shield/braid requirement (if any)

If you also need connectors: Thermocouple connectors (mini/standard) are available here.

Frequently Asked Questions (Shipping & Sales)

What is the most critical point when choosing a cable?

For thermocouples, type compatibility is key. For PT100, the 2/3/4-wire structure and insulation suitability are the most critical factors.

When will my order be shipped?

In-stock items are typically shipped the same day or the next business day. Lead times may vary for custom cut/length requests.

Is there an exchange/return option?

Return/exchange conditions apply for standard items. Different conditions may apply for custom cut/length requests.
