Pyrosales – A Leading Supplier of Thermocouple Cable and Wire

Thermocouple Wire and Cable

Temperature is one of the most important units of measurement that industries monitor. It is extremely imperative that temperature be as accurate as possible. If it is not managed correctly it can result in poorer quality items. A great smelling perfume, now smells ordinary, food may have a different flavour or in the medical field mismanagement of temperature can result in being unable to use donated items, such as blood.

A thermocouple is a commonly used sensor for measuring temperature. The wire and cable for thermocouples and temperature sensors are a vital part of the construction, as they complete the circuit between the thermocouple and the RTD controller. Essentially, this is what carries the signal from the thermocouple to the RTD which converts the temperature into an accurate reading. The outer insulation around the thermocouple wires as well as some single conductors are colour coded for easy identification.

Pyrosales provide a wide range of temperature sensor wire and cables using various high performance materials. They have been manufactured at the highest quality.
Below is a description of the different materials used in thermocouple wire and cables, as well as the applications which they can be used in.

Synthetic cableSynthetic– these are made with a flexible ceramic fibre yarn, which can survive high temperatures. The insulation is over the jacket as well as the single conductors.

There are a variety of applications which would be appropriate to use these cables, including:

  • Heat treating
  • Steel and aluminium plants
  • Glass, ceramic and brick manufacturing
  • Replacement for beaded thermocouples
  • Soaking pits

fibreglass cableFibreglass- the overall jacket as well as the single conductors are protected using a fibreglass braid. In terms of insulation, a high temperature resin is impregnated into the cable.

Suitable applications for fibreglass wire and cable to be used, include, but not limited to:

  • Steel and aluminium plants
  • Heat treating
  • Foundries
  • Glass, ceramic and brick plants
  • Plastic processing equipment

PVC cablePVC- each conductor as well as the jacket are individually colour coded. It is a relatively inexpensive insulator. Because these cables are made of PVC, this allows them to easily be stripped and separated, which makes its flexibility superior and its assembly easy. The wires are also produced in a multi-pair construction, including copper drain wires. This means each pair of conductors are individually wrapped using an aluminium tape.

The applications which are well suited to PVC wire and cable include:

  • Laboratories
  • Industrial equipment testing
  • Automotive
  • Testing facilities

FEP/PFA/PTFE- each single conductor as well as the outer jacket is layered with FEP/PFA/PTFE. These wires are known to have exceptional moisture, chemical and abrasion resistance.

Applications which are suitable to use FEP/PFA/PTFE wires include:

  • Industrial equipment testing
  • Power generating plants
  • Petroleum plants
  • Field heat treating

 

tape cableTape- TFE tape is applied to each conductor, after which they are heat fused followed by the tape being applied over the conductors that make the overall jacket. The heat fused tape makes the cable construction a tough assembly. These wires have excellent moisture, chemical and abrasion resistance properties.

Tape wire and cable are fitting to many applications which include:

  • Aircraft composite bonding
  • Power Plants
  • Kilns
  • Petroleum Plants
  • Glass, ceramic and brick plants
