Extension and Compensating cables

Extension and Compensating Cables are designed to connect thermocouples to measurement instruments positioned at a distance from the temperature source.

Siccet offers extension and compensating cables with flexible or solid conductors, and a wide range of insulating materials, tailored to meet specific customer requirements.

Extension Cables: These cables are made using wires with the same nominal composition as the thermocouple they extend, but with broader tolerances. They are identified by the letter “X” following the thermocouple type, and adhere to DIN IEC 60584 standard. Commonly tested within a temperature range of 0°C to 200°C, Siccet supplies the extension cables types EX, KX, JX, NX, and TX.

Compensating Cables: These cables are made from lower cost conductor materials with the same thermoelectric properties as the thermocouple, but with a different nominal composition. They are marked with a “C” next to the thermocouple type, in compliance with DIN IEC 60584. Siccet’s compensating cables are: Bc, Kca/Kcb, Nc, Rcb, and Scb.

The choice between extension and compensating cables is often based on cost considerations or the required distance between the measurement point and the instrument.
