Applications
These compensation and extension cables are used with thermocouples for temperature measurements where hydrocarbons may be present. The individual screening of each pair limits the consequence of crosstalk.
Design
Conductor:
Metal in accordance with the thermocouple, either solid cross section 0.5 mm² (1 x 0.8 mm), 1.34 mm² (1 x 1.30 mm) or flexible cross-section 1 mm² (14 x 0.30 mm)
Insulation:
Polyvinyl chloride (PVC)
Individual screen:
Binder tape
Tinned copper drain wire
Aluminium backed polyester tape
Binder tape
Overall screen:
Binder tape
Tinned copper drain wire
Aluminium backed polyester tape
Outer sheath:
Polyvinyl chloride (PVC)
Colour: depends on thermocouple type
