Thermocouple Type N

Thermocouple Type N

Thermocouple Type N  has been developed with silicon content which provides:

• Much longer life due to improved oxidation resistance of the negative NN leg

• Longer exposure to high temperature without gradual drift EMF

• Better reliability of EMF drift and short term EMF changes. Please note that Aperam Alloys Rescal type K thermocouple has been developed with silicon content instead of aluminium content and problems listed above are considerably reduced.

However Thermocouple type N provides better resistance to oxidation at elevated temperatures and good lifetime in applications where sulfur is present.

Those advantages are particularly interesting for use in aerospace, nuclear or semi-conductors industries. Thermocouple type N  has been developed with silicon content content which provides much longer life, longer exposure to high temperature and better reliability of EMF drift and short term EMF changes.
