La gamme de ces produits se compose de deux
familles :
- Les fils résistants
de forme ronde ou relaminée en alliages standards
suivant la norme DIN 1774, ainsi que des alliages suivant spécification
client.
 
- Les fils en alliages métalliques
destinés à la réalisation de thermocouple,
de câbles de compensation ou d'extension, correspondant
aux différentes normes internationales.

1. Wires for thermocouples
(ANSI MC 96.1-1982)
Wires for Thermocouples (DIN) IEC 584, Part 1, Reference Tables
Fils pour Couples thermoélectriques (NFC 42-321)
The basic EMF values for the
different thermocouples are now internationally identical;
except types U and L, which are only standardized en DIN 43710/1985.
On the other hand the standards show different limits of error.
Declaration acc. to (DIN)
IEC 584:
| Thermocouple: |
type identification letter |
| Single leg: |
type identification letter
+ polarity marking ("P" or "N") |

1. Wires for extension leads/cables
(ANSI MC 96.1-1982)
Wires for extension cables(DIN) IEC 584, Part 3
Fils pour Câbles d'extension (NFC 42-324)
These wires are used for the
electrical connection between the open end of a thermocouple
and the reference junction in those installations where the
conductors of the thermocouple are not directly connected
to the reference junction. Wires for extension leads are manufactured
from conductors having the same nominal composition as those
of the corresponding thermocouple. Extension cables have only
to fulfill the basic EMF range of the thermocouple up to a
fixed temperature (ingeneral 200°C).
Declaration acc. to (DIN)
IEC 584:
| Extension cable: |
identification
letter of the thermocouple in question
+ letter "X" |
| Single wire
for extension cable: |
identification
letter of the thermocouple in question
+ polarity marking ("P" or "N")
+ letter "X"
+ classification of tolerance (1,2) |

1. Wires for compensating
leads/cables (ANSI MC 96.1-1982)
Wires for compensating cables(DIN) IEC 584, Part 3
Fils pour Câbles de compensation (NFC 42-324)
These wires are used for the
electrical connection between the open end of a thermocouple
and the reference junction in those installations where the
conductors of the thermocouple are not directly connected
to the reference junction. ANSI as well as IEC 584 interpret
the above as pairs of wire showing the same temperature-EMF-characteristic
as the thermocouple in question. The conduictors (wires),
however, have a nominal composition different from that of
the corresponding thermocouple. French standard NFC 42-324
interprets "Câbles de Compensation" as a pair
of wires differing from the thermocouple by nature (chemical
composition) or quality, that means either the chemical
composition or the inferior thermoelectrical quality (tolerance)
designates the quality "Câbles de Compensation".
Declaration acc. to (DIN)
IEC 584:
| Compensating
cable: |
identification
letter of the thermocouple in question
+ letter "C" (Compensation)
+ letter "A" or "B" (index of temperature
range) |
| Single wire
for compensating cable: |
identification
letter of the thermocouple in question
+ polarity marking ("P" or "N")
+ letter "C" (Compensation)
+ letter "A" or "B" (index of temperature
range) |
