Compensation cable type K AN 6 L-SIL 2x1.5 mm² 48249

Compensating cables – precision temperature measurement

The AN 6 l-SIL 2x1.5 compensating cable is a specialized cable designed to connect thermocouples to measuring devices. Its main task is to ensure the accuracy of temperature measurement by minimizing errors resulting from thermoelectric potential differences at the connections. The cable's construction, with conductors made of special alloys (Fe/Cu-Ni, Ni/Cr-Ni or Pt/Rh-Pt), guarantees compatibility with various types of thermocouples.

Construction and practical application

The cable consists of conductors made of appropriate materials, insulated with PVC, silicone, fluoropolymer or fiberglass – the choice of insulation is adapted to specific working conditions. The conductors are shielded with a braid of tinned steel or copper wires, which provides resistance to electromagnetic interference and signal stability. This cable is used in control and measurement technology, especially where high temperature measurement accuracy is required – e.g. in the food, chemical, metallurgical or energy industries. Because the compensating cable generates a thermoelectric voltage similar to that produced by the thermocouple itself (up to +200°C), it allows for reliable readings even at large distances between the sensor and the measuring device.

Key features and benefits

• Measurement accuracy: Ensured by the use of appropriate conductive materials and minimization of thermoelectric errors.
• Versatility: Availability of various insulation materials (PVC, silicone, fluoropolymer, fiberglass) allows the cable to be adapted to specific environmental and temperature conditions.
• Interference resistance: The braided shield protects the signal from the influence of electromagnetic interference, which translates into stable and reliable readings.
• Compatibility: The cable works with various types of thermocouples (K, N, R, S, B), making it a universal solution for many applications.
• Durability: The use of high-quality materials guarantees long life and reliable operation in demanding industrial conditions.
• Flexibility: The stranded or wire construction provides easy installation and routing of cables in tight spaces.
• Conductor resistance: Adapted to different types of thermocouples: Fe: 0.080 Mom/m CuNi: 0.327 Mom/m NiCr: 0.07 Mom/m Ni: 0.3 Mom/m PtRh: 0.023 Mom/m Pt: 0.041 Mom/m
• Test voltage: Ensures safety of use - conductor/conductor - 500 V; conductor/screen - 500 V; screen/screen - 500 V (for PVC, fluoropolymer and silicone insulation). For fiberglass conductor/conductor - 500 V.
