Applications
These compensation and extension cables are used with thermocouples for temperature measurements. They are well adapted to underground use in industrial applications where hydrocarbons may be present and mechanical protections are needed (rafinery areas, chemical plant...)
Design
Conductor:
Metal in accordance with the thermocouple,
- for single pair cables solid cross-section 1.34 mm² (1 x 1.30 mm) or stranded cross-section 1 mm² (14 x 0.30 mm)
- multipair cables : solid cross-section 0.5 mm² (1 x 0.8 mm)
Insulation:
Polyvinyl chloride (PVC)
Collective screen:
Polyester tape
Tinned copper drain wire
Aluminium/polyester tape
Inner sheath:
Polyvinyl chloride (PVC)
Armour:
Paraffin-waxed crepe paper
Double steel tape
Outer sheath:
Polyvinyl chloride (PVC)
Colour: depends on thermocouple type
Core identification
