Description
N Type Thermocouple is a reliable temperature sensor designed for accurate and stable temperature measurement in industrial and process applications. It is made using Nickel-Chromium-Silicon (NiCrSi) and Nickel-Silicon-Magnesium (NiSiMg) thermoelements and offers excellent resistance to oxidation and drift at elevated temperatures.
N Type Thermocouples are suitable for applications where long-term measurement stability and reliable performance are required. Compared with conventional base-metal thermocouples, Type N provides improved thermoelectric stability in high-temperature environments and good resistance to oxidation.
These thermocouples are available in different constructions, including mineral insulated, sheathed, probe type, duplex and simplex configurations, with suitable thermowells, connectors, extension cables and mounting arrangements as per application requirements.
FAQs
