What is an N thermocouple?

An N-type thermocouple is a temperature sensor composed of a chromel (nickel-chromium) and alumel (nickel-aluminium) alloy, allowing it to measure temperatures over a wide range and provide a fast response.

The N-type thermocouple is highly resistant to oxidation, making it ideal for applications in inert and slightly oxidising atmospheres. Thanks to its durability and affordability, the N-type thermocouple is a widely used option in industries such as manufacturing, metallurgy and the energy sector.

 

How does an N-type thermocouple probe work?

The operation of an N-type thermocouple probe is based on the generation of an electrical signal proportional to the temperature difference between its ends. When the junction of the two metals detects a thermal change, a voltage is produced that can be interpreted to accurately measure the temperature.

This operating principle, combined with the high sensitivity of the N-type thermocouple, allows for fast and reliable readings in a wide variety of applications. For best performance, it is essential to use a suitable N-type thermocouple cable, as its quality directly influences signal stability.

 

Measurement range of an N-type probe

The measurement range of a type N probe is one of the widest among temperature sensors, ranging from -200°C to 1,250°C, depending on the type of coating and sensor protection.

This wide measurement range makes the K-type thermocouple an ideal choice for high-temperature industrial environments, as well as for applications in furnaces, turbines, and heating systems. If you need to know the exact values based on temperature, you can consult the N-type thermocouple table.

 

How to choose the right type N thermocouple sensor?

To choose the right type N thermocouple sensor, it is essential to consider several factors.

The temperature range determines the most suitable type N temperature probe, ensuring stability in different environments. The type of insulation influences the sensor's resistance to adverse conditions such as humidity or corrosion.

Finally, choosing the right N-type thermocouple cable ensures a stable signal and reduces interference, optimising measurement accuracy.
