Uncompromised measurement results with copper cables

Copper cables : Reliably transmit resistance signals with copper cables

Copper cables are used to transmit the resistance signals from resistance thermometers and forward the signal from transducers to the PLC. To account for their use in various industries, including power plant engineering, the steel industry or furnace construction, copper cables are insulated with different materials. Cables made of nickel are also available for high-temperature applications.

The resistance of the copper cable can cause incorrect measurement results in resistance thermometers as it exhibits temperature-dependent resistance in a series circuit. To compensate for this, resistance thermometers are available with a 3 or 4-wire circuit. With a 4-wire circuit, the resistance of the copper wire no longer has any influence and the measured value is transmitted without any altering. Copper cables are protected against corrosion by silver or nickel plating.

In order to set them apart, the copper cables are labeled according to a standard color code. All cables can be protected by braids, foils or armor. The cables are protected against electromagnetic fields thanks to their stranded design.

  • Available as stranded and solid conductors
  • Wide range of insulation options
  • Insulation possible up to an ambient temperature of 400°C
  • High accuracy due to 3 and 4-wire connection
  • Protected against corrosion by silver or nickel plating
