Instrumentation and compensation cables

  • Oil&Gas Onshore InstrumentationFire-safe, “mud-resistant” LV and MV cables are used for control and instrumentation at wellheads and manifolds/gathering systems.
  • IEEE 45 Type P versions exist for explosion-risk environments.

Light-blue sheathed Intrinsically Safe (IS) cables are available for installing separate power circuits to ensure the safety of electrical equipment where flammable materials are present. The PVC outer jacket is resistant to oil and gas, as well as being flame-resistant.

These cables are used to transmit analogue or digital signals in measurement and process control. Unarmoured cables can be used where there is no risk of mechanical damages.

Armoured cables are well adapted to underground use in industrial applications where chemical and mechanical protection ar needed. Lead covered and armoured cables are hydrocarbons resistant and have an enhanced resistance to aromatics. The Hypron® types offer an alternative to lead caveved cables.

AFNOR NF M 87 202 (250 V) is PVC insulation with PVC outer sheath type.
PAS 5308 (300/500 V) and EN 50288-7 (170/300 V) are PVC insulation with PVC outer sheath and XLPE, silicone and Mica tape/XLPE insulation with PVC sheath types.

   
Thermocouple cables
Special Cables/Oil & Gas - Petrochemical dedicated cables

Thermocouples are a widely used type of temperature sensor. They can measure a wide range of temperatures, they are very simple in operation and measure the temperature between two points.

A thermocouple construction consists of two dissimilar metal wire welded together at the measuring point and insulated from each other. It will usually have an outer protection sheath.

If two conductors of different materials are joined at one point, an EMF (electromotrice force) is created between the open ends which is dependent upon the temperature of the junction. In most applications, one of the junctions — the "cold junction" — is maintained at a known (reference) temperature, while the other end is attached to a probe. Another temperature sensor will measure the temperature at this point, so that the temperature at the probe tip can be calculated.

Usually the thermocouple is attached to the indicating device by a special wire...
