Isıso Thermocouple and PT100 Compensation Cables

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.

How to choose Thermocouple and PT100 Compensation Cables

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.

  • Clarify the circuit duty first: power distribution, control, fire safety, Ethernet or analog signal.
  • Compare conductor cross-section, core count, insulation and shielding against the installation route.
  • Switch to the proper cable family early when flex duty, oil resistance, halogen-free jacket or fire integrity is required.
