ВОт контекст:When making measurements where additional wires have to be connected to the thermocouple leads, care must be
exercised in selecting these wire types, not only where they are claimed to be of the same composition as the
thermocouple involved, but, also, of their "quality".
Performance results where high precision is required and in circumstances where some types of thermocouple wire leads
are added to the original installation should be reviewed carefully for the impact of the choice of the additional wire leads.
The quality of thermocouple wire is established by the limit of error to be expected with its use.
There are three recognizable levels of quality:
- Special or Premium grade
- Standard grade
- Extension wire grade
The error limits determining the grade quality differ from thermocouple type to thermocouple type, reflecting the degree of
difficulty in maintaining the precise levels of purity of the metal used.
The table below summarizes the error limits for Premium and Standard grades, while Extension grade wire is
characterized by limits of error exceeding those in the table. Заранее благодарен!
