Thermocouple and PT100 Compensation Cables Selection Guide: Technical Criteria & Application Standards
Thermocouple and PT100 Compensation Cables selection guide: technical parameters, mounting and compliance standards, and Isıso comparison.
A thermocouple compensation cable is a measurement cable that extends the line between a thermocouple and a measuring instrument without distorting the thermoelectric voltage, with conductors made of alloys matching the thermocouple type; a PT100 cable is a multi-core connection cable that connects a resistance thermometer to the instrument. In furnaces, extruders, injection molding machines and process lines, it carries the sensor signal to the measuring instrument in the panel, to a transmitter or to a PLC temperature module. In this category, Isıso-brand Fe-Const (type J) and NiCr-Ni (type K) thermocouple cables in cross-sections such as 2 x 0.22 mm², 2 x 0.75 mm² and 2 x 1.5 mm², and PT100 cables in 2-, 3- and 4-core 0.22 mm² constructions, with silicone sheath or steel braid, are sold by the meter. Choose the cable type according to the sensor (J, K or PT100); on a PT100 cable, choose the number of cores according to whether the connection is 2-, 3- or 4-wire, the cross-section according to the line length, and the outer sheath according to the ambient temperature and mechanical stress. A copper-conductor signal cable does not replace a thermocouple compensation cable; the temperature difference between the junction point and the instrument shows up as a measurement error. The Thermocouple and PT100 Compensation Cables category on Welibaba includes 13 active models from leading manufacturers such as Isıso.
Key Technical Parameters for Selecting Thermocouple and PT100 Compensation Cables
To specify the right Thermocouple and PT100 Compensation Cables model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |

| Cable Cross-Section | 2 x 0, 22 mm², 2x0, 75 mm² | Verify against project schedule and load calculation |
| Thermocouple Type | Fe-Const (J), NiCr-Ni (K), PT100 | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Industrial and Communication Cables.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Programming and Communication Cables, EIB-BUS Cables, Load Cell Cables.
