Conductors made of special metal alloys. Insulation and sheath: PVC, SiR, HFFR, FEP, PFA, glass fibre or basalt fibre. CuSn screen; FeZn or AISI 304 armour. Construction depends on the agreed specification.
Standards
IEC 584-3; DIN 43714; BS 1843; NF C 42-324; ANSI/MC 96-1
Application
Compensation and extension cables (thermoelectric) are an element of the measuring system connecting the thermoelectric sensor with the measuring device, e.g. a controller, indicator or temperature recorder..
Technical tables
Material pairs and working temperatures
| Insulation / sheath | Temperature [°C] |
|---|---|
| PVC / PVC | −25…+105 |
| SiR / SiR | −60…+200 |
| HFFR / HFFR | −40…+120 |
| FEP / FEP | −90…+205 |
| PFA / PFA | −90…+260 |
| GL / GL | −60…+400 |
| BB / BB | −60…+750 |
These are not thermocouple measurement or compensation ranges. Mixed constructions require individual confirmation.
Available versions
The designation describes the thermoelement type, insulation, conductor construction, sheath, screen, number of pairs and conductor cross-section. The source scheme lists 1–8 pairs and 0.22; 0.5; 0.75; 1; 1.5; 2.5 mm². These values are not a promise that every combination is available. Final construction is agreed individually. Cable diameter is available on request.
